+ *
+ ****************************************************************************
+ *
+ * Version 0.1.12
+ *
+ * The ANSI C standard committee, for the C99 standard, specified the
+ * inclusion of a new standard include file called stdint.h. This is
+ * a very useful and long desired include file which contains several
+ * very precise definitions for integer scalar types that is
+ * critically important for making portable several classes of
+ * applications including cryptography, hashing, variable length
+ * integer libraries and so on. But for most developers its likely
+ * useful just for programming sanity.
+ *
+ * The problem is that most compiler vendors have decided not to
+ * implement the C99 standard, and the next C++ language standard
+ * (which has a lot more mindshare these days) will be a long time in
+ * coming and its unknown whether or not it will include stdint.h or
+ * how much adoption it will have. Either way, it will be a long time
+ * before all compilers come with a stdint.h and it also does nothing
+ * for the extremely large number of compilers available today which
+ * do not include this file, or anything comparable to it.
+ *
+ * So that's what this file is all about. Its an attempt to build a
+ * single universal include file that works on as many platforms as
+ * possible to deliver what stdint.h is supposed to. A few things
+ * that should be noted about this file:
+ *
+ * 1) It is not guaranteed to be portable and/or present an identical
+ * interface on all platforms. The extreme variability of the
+ * ANSI C standard makes this an impossibility right from the
+ * very get go. Its really only meant to be useful for the vast
+ * majority of platforms that possess the capability of
+ * implementing usefully and precisely defined, standard sized
+ * integer scalars. Systems which are not intrinsically 2s
+ * complement may produce invalid constants.
+ *
+ * 2) There is an unavoidable use of non-reserved symbols.
+ *
+ * 3) Other standard include files are invoked.
+ *
+ * 4) This file may come in conflict with future platforms that do
+ * include stdint.h. The hope is that one or the other can be
+ * used with no real difference.
+ *
+ * 5) In the current verison, if your platform can't represent
+ * int32_t, int16_t and int8_t, it just dumps out with a compiler
+ * error.
+ *
+ * 6) 64 bit integers may or may not be defined. Test for their
+ * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
+ * Note that this is different from the C99 specification which
+ * requires the existence of 64 bit support in the compiler. If
+ * this is not defined for your platform, yet it is capable of
+ * dealing with 64 bits then it is because this file has not yet
+ * been extended to cover all of your system's capabilities.
+ *
+ * 7) (u)intptr_t may or may not be defined. Test for its presence
+ * with the test: #ifdef PTRDIFF_MAX. If this is not defined
+ * for your platform, then it is because this file has not yet
+ * been extended to cover all of your system's capabilities, not
+ * because its optional.
+ *
+ * 8) The following might not been defined even if your platform is
+ * capable of defining it:
+ *
+ * WCHAR_MIN
+ * WCHAR_MAX
+ * (u)int64_t
+ * PTRDIFF_MIN
+ * PTRDIFF_MAX
+ * (u)intptr_t
+ *
+ * 9) The following have not been defined:
+ *
+ * WINT_MIN
+ * WINT_MAX
+ *
+ * 10) The criteria for defining (u)int_least(*)_t isn't clear,
+ * except for systems which don't have a type that precisely
+ * defined 8, 16, or 32 bit types (which this include file does
+ * not support anyways). Default definitions have been given.
+ *
+ * 11) The criteria for defining (u)int_fast(*)_t isn't something I
+ * would trust to any particular compiler vendor or the ANSI C
+ * committee. It is well known that "compatible systems" are
+ * commonly created that have very different performance
+ * characteristics from the systems they are compatible with,
+ * especially those whose vendors make both the compiler and the
+ * system. Default definitions have been given, but its strongly
+ * recommended that users never use these definitions for any
+ * reason (they do *NOT* deliver any serious guarantee of
+ * improved performance -- not in this file, nor any vendor's
+ * stdint.h).
+ *
+ * 12) The following macros:
+ *
+ * PRINTF_INTMAX_MODIFIER
+ * PRINTF_INT64_MODIFIER
+ * PRINTF_INT32_MODIFIER
+ * PRINTF_INT16_MODIFIER
+ * PRINTF_LEAST64_MODIFIER
+ * PRINTF_LEAST32_MODIFIER
+ * PRINTF_LEAST16_MODIFIER
+ * PRINTF_INTPTR_MODIFIER
+ *
+ * are strings which have been defined as the modifiers required
+ * for the "d", "u" and "x" printf formats to correctly output
+ * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
+ * (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
+ * PRINTF_INTPTR_MODIFIER is not defined for some systems which
+ * provide their own stdint.h. PRINTF_INT64_MODIFIER is not
+ * defined if INT64_MAX is not defined. These are an extension
+ * beyond what C99 specifies must be in stdint.h.
+ *
+ * In addition, the following macros are defined:
+ *
+ * PRINTF_INTMAX_HEX_WIDTH
+ * PRINTF_INT64_HEX_WIDTH
+ * PRINTF_INT32_HEX_WIDTH
+ * PRINTF_INT16_HEX_WIDTH
+ * PRINTF_INT8_HEX_WIDTH
+ * PRINTF_INTMAX_DEC_WIDTH
+ * PRINTF_INT64_DEC_WIDTH
+ * PRINTF_INT32_DEC_WIDTH
+ * PRINTF_INT16_DEC_WIDTH
+ * PRINTF_INT8_DEC_WIDTH
+ *
+ * Which specifies the maximum number of characters required to
+ * print the number of that type in either hexadecimal or decimal.
+ * These are an extension beyond what C99 specifies must be in
+ * stdint.h.
+ *
+ * Compilers tested (all with 0 warnings at their highest respective
+ * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
+ * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
+ * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
+ *
+ * This file should be considered a work in progress. Suggestions for
+ * improvements, especially those which increase coverage are strongly
+ * encouraged.
+ *
+ * Acknowledgements
+ *
+ * The following people have made significant contributions to the
+ * development and testing of this file:

+ registers for 4::2 parallelism.
+All 1-bit deltas, all 2-bit deltas, all deltas composed of top bits of
+ (a,b,c), and all deltas of bottom bits were tested. All deltas were
+ tested both on random keys and on keys that were nearly all zero.
+ These deltas all cause every bit of c to change between 1/3 and 2/3
+ of the time (well, only 113/400 to 287/400 of the time for some
+ 2-bit delta). These deltas all cause at least 80 bits to change
+ among (a,b,c) when the mix is run either forward or backward (yes it
+ is reversible).
+This implies that a hash using mix64 has no funnels. There may be
+ characteristics with 3-bit deltas or bigger, I didn't test for
+ those.

+ k : the key (the unaligned variable-length array of bytes)
+ len : the length of the key, counting by bytes
+ level : can be any 8-byte value
+Returns a 64-bit value. Every bit of the key affects every bit of
+the return value. No funnels. Every 1-bit and 2-bit delta achieves
+avalanche. About 41+5len instructions.
+
+The best hash table sizes are powers of 2. There is no need to do
+mod a prime (mod is sooo slow!). If you need less than 64 bits,
+use a bitmask. For example, if you need only 10 bits, do
+ h = (h & hashmask(10));
+In which case, the hash table should have hashsize(10) elements.
+
+If you are hashing n strings (ub1 **)k, do it like this:
+ for (i=0, h=0; i<n; ++i) h = hash( k[i], len[i], h);

+Better String library
+---------------------
+
+by Paul Hsieh
+
+The bstring library is an attempt to provide improved string processing
+functionality to the C and C++ language. At the heart of the bstring library
+(Bstrlib for short) is the management of "bstring"s which are a significant
+improvement over '\0' terminated char buffers.
+
+===============================================================================
+
+Motivation
+----------
+
+The standard C string library has serious problems:
+
+ 1) Its use of '\0' to denote the end of the string means knowing a
+ string's length is O(n) when it could be O(1).
+ 2) It imposes an interpretation for the character value '\0'.
+ 3) gets() always exposes the application to a buffer overflow.
+ 4) strtok() modifies the string its parsing and thus may not be usable in
+ programs which are re-entrant or multithreaded.
+ 5) fgets has the unusual semantic of ignoring '\0's that occur before
+ '\n's are consumed.
+ 6) There is no memory management, and actions performed such as strcpy,
+ strcat and sprintf are common places for buffer overflows.
+ 7) strncpy() doesn't '\0' terminate the destination in some cases.
+ 8) Passing NULL to C library string functions causes an undefined NULL
+ pointer access.
+ 9) Parameter aliasing (overlapping, or self-referencing parameters)
+ within most C library functions has undefined behavior.
+ 10) Many C library string function calls take integer parameters with
+ restricted legal ranges. Parameters passed outside these ranges are
+ not typically detected and cause undefined behavior.
+
+So the desire is to create an alternative string library that does not suffer
+from the above problems and adds in the following functionality:
+
+ 1) Incorporate string functionality seen from other languages.
+ a) MID$() - from BASIC
+ b) split()/join() - from Python
+ c) string/char x n - from Perl
+ 2) Implement analogs to functions that combine stream IO and char buffers
+ without creating a dependency on stream IO functionality.
+ 3) Implement the basic text editor-style functions insert, delete, find,
+ and replace.
+ 4) Implement reference based sub-string access (as a generalization of
+ pointer arithmetic.)
+ 5) Implement runtime write protection for strings.
+
+There is also a desire to avoid "API-bloat". So functionality that can be
+implemented trivially in other functionality is omitted. So there is no
+left$() or right$() or reverse() or anything like that as part of the core
+functionality.
+
+Explaining Bstrings
+-------------------
+
+A bstring is basically a header which wraps a pointer to a char buffer. Lets
+start with the declaration of a struct tagbstring:
+
+ struct tagbstring {
+ int mlen;
+ int slen;
+ unsigned char * data;
+ };
+
+This definition is considered exposed, not opaque (though it is neither
+necessary nor recommended that low level maintenance of bstrings be performed
+whenever the abstract interfaces are sufficient). The mlen field (usually)
+describes a lower bound for the memory allocated for the data field. The
+slen field describes the exact length for the bstring. The data field is a
+single contiguous buffer of unsigned chars. Note that the existence of a '\0'
+character in the unsigned char buffer pointed to by the data field does not
+necessarily denote the end of the bstring.
+
+To be a well formed modifiable bstring the mlen field must be at least the
+length of the slen field, and slen must be non-negative. Furthermore, the
+data field must point to a valid buffer in which access to the first mlen
+characters has been acquired. So the minimal check for correctness is:
+
+ (slen >= 0 && mlen >= slen && data != NULL)
+
+bstrings returned by bstring functions can be assumed to be either NULL or
+satisfy the above property. (When bstrings are only readable, the mlen >=
+slen restriction is not required; this is discussed later in this section.)
+A bstring itself is just a pointer to a struct tagbstring:
+
+ typedef struct tagbstring * bstring;
+
+Note that use of the prefix "tag" in struct tagbstring is required to work
+around the inconsistency between C and C++'s struct namespace usage. This
+definition is also considered exposed.
+
+Bstrlib basically manages bstrings allocated as a header and an associated
+data-buffer. Since the implementation is exposed, they can also be
+constructed manually. Functions which mutate bstrings assume that the header
+and data buffer have been malloced; the bstring library may perform free() or
+realloc() on both the header and data buffer of any bstring parameter.
+Functions which return bstring's create new bstrings. The string memory is
+freed by a bdestroy() call (or using the bstrFree macro).
+
+The following related typedef is also provided:
+
+ typedef const struct tagbstring * const_bstring;
+
+which is also considered exposed. These are directly bstring compatible (no
+casting required) but are just used for parameters which are meant to be
+non-mutable. So in general, bstring parameters which are read as input but
+not meant to be modified will be declared as const_bstring, and bstring
+parameters which may be modified will be declared as bstring. This convention
+is recommended for user written functions as well.
+
+Since bstrings maintain interoperability with C library char-buffer style
+strings, all functions which modify, update or create bstrings also append a
+'\0' character into the position slen + 1. This trailing '\0' character is
+not required for bstrings input to the bstring functions; this is provided
+solely as a convenience for interoperability with standard C char-buffer
+functionality.
+
+Analogs for the ANSI C string library functions have been created when they
+are necessary, but have also been left out when they are not. In particular
+there are no functions analogous to fwrite, or puts just for the purposes of
+bstring. The ->data member of any string is exposed, and therefore can be
+used just as easily as char buffers for C functions which read strings.
+
+For those that wish to hand construct bstrings, the following should be kept
+in mind:
+
+ 1) While bstrlib can accept constructed bstrings without terminating
+ '\0' characters, the rest of the C language string library will not
+ function properly on such non-terminated strings. This is obvious
+ but must be kept in mind.
+ 2) If it is intended that a constructed bstring be written to by the
+ bstring library functions then the data portion should be allocated
+ by the malloc function and the slen and mlen fields should be entered
+ properly. The struct tagbstring header is not reallocated, and only
+ freed by bdestroy.
+ 3) Writing arbitrary '\0' characters at various places in the string
+ will not modify its length as perceived by the bstring library
+ functions. In fact, '\0' is a legitimate non-terminating character
+ for a bstring to contain.
+ 4) For read only parameters, bstring functions do not check the mlen.
+ I.e., the minimal correctness requirements are reduced to:
+
+ (slen >= 0 && data != NULL)
+
+Better pointer arithmetic
+-------------------------
+
+One built-in feature of '\0' terminated char * strings, is that its very easy
+and fast to obtain a reference to the tail of any string using pointer
+arithmetic. Bstrlib does one better by providing a way to get a reference to
+any substring of a bstring (or any other length delimited block of memory.)
+So rather than just having pointer arithmetic, with bstrlib one essentially
+has segment arithmetic. This is achieved using the macro blk2tbstr() which
+builds a reference to a block of memory and the macro bmid2tbstr() which
+builds a reference to a segment of a bstring. Bstrlib also includes
+functions for direct consumption of memory blocks into bstrings, namely
+bcatblk () and blk2bstr ().
+
+One scenario where this can be extremely useful is when string contains many
+substrings which one would like to pass as read-only reference parameters to
+some string consuming function without the need to allocate entire new
+containers for the string data. More concretely, imagine parsing a command
+line string whose parameters are space delimited. This can only be done for
+tails of the string with '\0' terminated char * strings.
+
+Improved NULL semantics and error handling
+------------------------------------------
+
+Unless otherwise noted, if a NULL pointer is passed as a bstring or any other
+detectably illegal parameter, the called function will return with an error
+indicator (either NULL or BSTR_ERR) rather than simply performing a NULL
+pointer access, or having undefined behavior.
+
+To illustrate the value of this, consider the following example:
+
+ strcpy (p = malloc (13 * sizeof (char)), "Hello,");
+ strcat (p, " World");
+
+This is not correct because malloc may return NULL (due to an out of memory
+condition), and the behaviour of strcpy is undefined if either of its
+parameters are NULL. However:
+
+ bstrcat (p = bfromcstr ("Hello,"), q = bfromcstr (" World"));
+ bdestroy (q);
+
+is well defined, because if either p or q are assigned NULL (indicating a
+failure to allocate memory) both bstrcat and bdestroy will recognize it and
+perform no detrimental action.
+
+Note that it is not necessary to check any of the members of a returned
+bstring for internal correctness (in particular the data member does not need
+to be checked against NULL when the header is non-NULL), since this is
+assured by the bstring library itself.
+
+bStreams
+--------
+
+In addition to the bgets and bread functions, bstrlib can abstract streams
+with a high performance read only stream called a bStream. In general, the
+idea is to open a core stream (with something like fopen) then pass its
+handle as well as a bNread function pointer (like fread) to the bsopen
+function which will return a handle to an open bStream. Then the functions
+bsread, bsreadln or bsreadlns can be called to read portions of the stream.
+Finally, the bsclose function is called to close the bStream -- it will
+return a handle to the original (core) stream. So bStreams, essentially,
+wrap other streams.
+
+The bStreams have two main advantages over the bgets and bread (as well as
+fgets/ungetc) paradigms:
+
+1) Improved functionality via the bunread function which allows a stream to
+ unread characters, giving the bStream stack-like functionality if so
+ desired.
+2) A very high performance bsreadln function. The C library function fgets()
+ (and the bgets function) can typically be written as a loop on top of
+ fgetc(), thus paying all of the overhead costs of calling fgetc on a per
+ character basis. bsreadln will read blocks at a time, thus amortizing the
+ overhead of fread calls over many characters at once.
+
+However, clearly bStreams are suboptimal or unusable for certain kinds of
+streams (stdin) or certain usage patterns (a few spotty, or non-sequential
+reads from a slow stream.) For those situations, using bgets will be more
+appropriate.
+
+The semantics of bStreams allows practical construction of layerable data
+streams. What this means is that by writing a bNread compatible function on
+top of a bStream, one can construct a new bStream on top of it. This can be
+useful for writing multi-pass parsers that don't actually read the entire
+input more than once and don't require the use of intermediate storage.
+
+Aliasing
+--------
+
+Aliasing occurs when a function is given two parameters which point to data
+structures which overlap in the memory they occupy. While this does not
+disturb read only functions, for many libraries this can make functions that
+write to these memory locations malfunction. This is a common problem of the
+C standard library and especially the string functions in the C standard
+library.
+
+The C standard string library is entirely char by char oriented (as is
+bstring) which makes conforming implementations alias safe for some
+scenarios. However no actual detection of aliasing is typically performed,
+so it is easy to find cases where the aliasing will cause anomolous or
+undesirable behaviour (consider: strcat (p, p).) The C99 standard includes
+the "restrict" pointer modifier which allows the compiler to document and
+assume a no-alias condition on usage. However, only the most trivial cases
+can be caught (if at all) by the compiler at compile time, and thus there is
+no actual enforcement of non-aliasing.
+
+Bstrlib, by contrast, permits aliasing and is completely aliasing safe, in
+the C99 sense of aliasing. That is to say, under the assumption that
+pointers of incompatible types from distinct objects can never alias, bstrlib
+is completely aliasing safe. (In practice this means that the data buffer
+portion of any bstring and header of any bstring are assumed to never alias.)
+With the exception of the reference building macros, the library behaves as
+if all read-only parameters are first copied and replaced by temporary
+non-aliased parameters before any writing to any output bstring is performed
+(though actual copying is extremely rarely ever done.)
+
+Besides being a useful safety feature, bstring searching/comparison
+functions can improve to O(1) execution when aliasing is detected.
+
+Note that aliasing detection and handling code in Bstrlib is generally
+extremely cheap. There is almost never any appreciable performance penalty
+for using aliased parameters.
+
+Reenterancy
+-----------
+
+Nearly every function in Bstrlib is a leaf function, and is completely
+reenterable with the exception of writing to common bstrings. The split
+functions which use a callback mechanism requires only that the source string
+not be destroyed by the callback function unless the callback function returns
+with an error status (note that Bstrlib functions which return an error do
+not modify the string in any way.) The string can in fact be modified by the
+callback and the behaviour is deterministic. See the documentation of the
+various split functions for more details.
+
+Undefined scenarios
+-------------------
+
+One of the basic important premises for Bstrlib is to not to increase the
+propogation of undefined situations from parameters that are otherwise legal
+in of themselves. In particular, except for extremely marginal cases, usages
+of bstrings that use the bstring library functions alone cannot lead to any
+undefined action. But due to C/C++ language and library limitations, there
+is no way to define a non-trivial library that is completely without
+undefined operations. All such possible undefined operations are described
+below:
+
+1) bstrings or struct tagbstrings that are not explicitely initialized cannot
+ be passed as a parameter to any bstring function.
+2) The members of the NULL bstring cannot be accessed directly. (Though all
+ APIs and macros detect the NULL bstring.)
+3) A bstring whose data member has not been obtained from a malloc or
+ compatible call and which is write accessible passed as a writable
+ parameter will lead to undefined results. (i.e., do not writeAllow any
+ constructed bstrings unless the data portion has been obtained from the
+ heap.)
+4) If the headers of two strings alias but are not identical (which can only
+ happen via a defective manual construction), then passing them to a
+ bstring function in which one is writable is not defined.
+5) If the mlen member is larger than the actual accessible length of the data
+ member for a writable bstring, or if the slen member is larger than the
+ readable length of the data member for a readable bstring, then the
+ corresponding bstring operations are undefined.
+6) Any bstring definition whose header or accessible data portion has been
+ assigned to inaccessible or otherwise illegal memory clearly cannot be
+ acted upon by the bstring library in any way.
+7) Destroying the source of an incremental split from within the callback
+ and not returning with a negative value (indicating that it should abort)
+ will lead to undefined behaviour. (Though *modifying* or adjusting the
+ state of the source data, even if those modification fail within the
+ bstrlib API, has well defined behavior.)
+8) Modifying a bstring which is write protected by direct access has
+ undefined behavior.
+
+While this may seem like a long list, with the exception of invalid uses of
+the writeAllow macro, and source destruction during an iterative split
+without an accompanying abort, no usage of the bstring API alone can cause
+any undefined scenario to occurr. I.e., the policy of restricting usage of
+bstrings to the bstring API can significantly reduce the risk of runtime
+errors (in practice it should eliminate them) related to string manipulation
+due to undefined action.
+
+C++ wrapper
+-----------
+
+A C++ wrapper has been created to enable bstring functionality for C++ in the
+most natural (for C++ programers) way possible. The mandate for the C++
+wrapper is different from the base C bstring library. Since the C++ language
+has far more abstracting capabilities, the CBString structure is considered
+fully abstracted -- i.e., hand generated CBStrings are not supported (though
+conversion from a struct tagbstring is allowed) and all detectable errors are
+manifest as thrown exceptions.
+
+- The C++ class definitions are all under the namespace Bstrlib. bstrwrap.h
+ enables this namespace (with a using namespace Bstrlib; directive at the
+ end) unless the macro BSTRLIB_DONT_ASSUME_NAMESPACE has been defined before
+ it is included.
+
+- Erroneous accesses results in an exception being thrown. The exception
+ parameter is of type "struct CBStringException" which is derived from
+ std::exception if STL is used. A verbose description of the error message
+ can be obtained from the what() method.
+
+- CBString is a C++ structure derived from a struct tagbstring. An address
+ of a CBString cast to a bstring must not be passed to bdestroy. The bstring
+ C API has been made C++ safe and can be used directly in a C++ project.
+
+- It includes constructors which can take a char, '\0' terminated char
+ buffer, tagbstring, (char, repeat-value), a length delimited buffer or a
+ CBStringList to initialize it.
+
+- Concatenation is performed with the + and += operators. Comparisons are
+ done with the ==, !=, <, >, <= and >= operators. Note that == and != use
+ the biseq call, while <, >, <= and >= use bstrcmp.
+
+- CBString's can be directly cast to const character buffers.
+
+- CBString's can be directly cast to double, float, int or unsigned int so
+ long as the CBString are decimal representations of those types (otherwise
+ an exception will be thrown). Converting the other way should be done with
+ the format(a) method(s).
+
+- CBString contains the length, character and [] accessor methods. The
+ character and [] accessors are aliases of each other. If the bounds for
+ the string are exceeded, an exception is thrown. To avoid the overhead for
+ this check, first cast the CBString to a (const char *) and use [] to
+ dereference the array as normal. Note that the character and [] accessor
+ methods allows both reading and writing of individual characters.
+
+- The methods: format, formata, find, reversefind, findcaseless,
+ reversefindcaseless, midstr, insert, insertchrs, replace, findreplace,
+ findreplacecaseless, remove, findchr, nfindchr, alloc, toupper, tolower,
+ gets, read are analogous to the functions that can be found in the C API.
+
+- The caselessEqual and caselessCmp methods are analogous to biseqcaseless
+ and bstricmp functions respectively.
+
+- Note that just like the bformat function, the format and formata methods do
+ not automatically cast CBStrings into char * strings for "%s"-type
+ substitutions:
+
+ CBString w("world");
+ CBString h("Hello");
+ CBString hw;
+
+ /* The casts are necessary */
+ hw.format ("%s, %s", (const char *)h, (const char *)w);
+
+- The methods trunc and repeat have been added instead of using pattern.
+
+- ltrim, rtrim and trim methods have been added. These remove characters
+ from a given character string set (defaulting to the whitespace characters)
+ from either the left, right or both ends of the CBString, respectively.
+
+- The method setsubstr is also analogous in functionality to bsetstr, except
+ that it cannot be passed NULL. Instead the method fill and the fill-style
+ constructor have been supplied to enable this functionality.
+
+- The writeprotect(), writeallow() and iswriteprotected() methods are
+ analogous to the bwriteprotect(), bwriteallow() and biswriteprotected()
+ macros in the C API. Write protection semantics in CBString are stronger
+ than with the C API in that indexed character assignment is checked for
+ write protection. However, unlike with the C API, a write protected
+ CBString can be destroyed by the destructor.
+
+- CBStream is a C++ structure which wraps a struct bStream (its not derived
+ from it, since destruction is slightly different). It is constructed by
+ passing in a bNread function pointer and a stream parameter cast to void *.
+ This structure includes methods for detecting eof, setting the buffer
+ length, reading the whole stream or reading entries line by line or block
+ by block, an unread function, and a peek function.
+
+- If STL is available, the CBStringList structure is derived from a vector of
+ CBString with various split methods. The split method has been overloaded
+ to accept either a character or CBString as the second parameter (when the
+ split parameter is a CBString any character in that CBString is used as a
+ seperator). The splitstr method takes a CBString as a substring seperator.
+ Joins can be performed via a CBString constructor which takes a
+ CBStringList as a parameter, or just using the CBString::join() method.
+
+- If there is proper support for std::iostreams, then the >> and << operators
+ and the getline() function have been added (with semantics the same as
+ those for std::string).
+
+Multithreading
+--------------
+
+A mutable bstring is kind of analogous to a small (two entry) linked list
+allocated by malloc, with all aliasing completely under programmer control.
+I.e., manipulation of one bstring will never affect any other distinct
+bstring unless explicitely constructed to do so by the programmer via hand
+construction or via building a reference. Bstrlib also does not use any
+static or global storage, so there are no hidden unremovable race conditions.
+Bstrings are also clearly not inherently thread local. So just like
+char *'s, bstrings can be passed around from thread to thread and shared and
+so on, so long as modifications to a bstring correspond to some kind of
+exclusive access lock as should be expected (or if the bstring is read-only,
+which can be enforced by bstring write protection) for any sort of shared
+object in a multithreaded environment.
+
+Bsafe module
+------------
+
+For convenience, a bsafe module has been included. The idea is that if this
+module is included, inadvertant usage of the most dangerous C functions will
+be overridden and lead to an immediate run time abort. Of course, it should
+be emphasized that usage of this module is completely optional. The
+intention is essentially to provide an option for creating project safety
+rules which can be enforced mechanically rather than socially. This is
+useful for larger, or open development projects where its more difficult to
+enforce social rules or "coding conventions".
+
+Problems not solved
+-------------------
+
+Bstrlib is written for the C and C++ languages, which have inherent weaknesses
+that cannot be easily solved:
+
+1. Memory leaks: Forgetting to call bdestroy on a bstring that is about to be
+ unreferenced, just as forgetting to call free on a heap buffer that is
+ about to be dereferenced. Though bstrlib itself is leak free.
+2. Read before write usage: In C, declaring an auto bstring does not
+ automatically fill it with legal/valid contents. This problem has been
+ somewhat mitigated in C++. (The bstrDeclare and bstrFree macros from
+ bstraux can be used to help mitigate this problem.)
+
+Other problems not addressed:
+
+3. Built-in mutex usage to automatically avoid all bstring internal race
+ conditions in multitasking environments: The problem with trying to
+ implement such things at this low a level is that it is typically more
+ efficient to use locks in higher level primitives. There is also no
+ platform independent way to implement locks or mutexes.
+4. Unicode/widecharacter support.
+
+Note that except for spotty support of wide characters, the default C
+standard library does not address any of these problems either.
+
+Configurable compilation options
+--------------------------------
+
+All configuration options are meant solely for the purpose of compiler
+compatibility. Configuration options are not meant to change the semantics
+or capabilities of the library, except where it is unavoidable.
+
+Since some C++ compilers don't include the Standard Template Library and some
+have the options of disabling exception handling, a number of macros can be
+used to conditionally compile support for each of this:
+
+BSTRLIB_CAN_USE_STL
+
+ - defining this will enable the used of the Standard Template Library.
+ Defining BSTRLIB_CAN_USE_STL overrides the BSTRLIB_CANNOT_USE_STL macro.
+
+BSTRLIB_CANNOT_USE_STL
+
+ - defining this will disable the use of the Standard Template Library.
+ Defining BSTRLIB_CAN_USE_STL overrides the BSTRLIB_CANNOT_USE_STL macro.
+
+BSTRLIB_CAN_USE_IOSTREAM
+
+ - defining this will enable the used of streams from class std. Defining
+ BSTRLIB_CAN_USE_IOSTREAM overrides the BSTRLIB_CANNOT_USE_IOSTREAM macro.
+
+BSTRLIB_CANNOT_USE_IOSTREAM
+
+ - defining this will disable the use of streams from class std. Defining
+ BSTRLIB_CAN_USE_IOSTREAM overrides the BSTRLIB_CANNOT_USE_IOSTREAM macro.
+
+BSTRLIB_THROWS_EXCEPTIONS
+
+ - defining this will enable the exception handling within bstring.
+ Defining BSTRLIB_THROWS_EXCEPTIONS overrides the
+ BSTRLIB_DOESNT_THROWS_EXCEPTIONS macro.
+
+BSTRLIB_DOESNT_THROW_EXCEPTIONS
+
+ - defining this will disable the exception handling within bstring.
+ Defining BSTRLIB_THROWS_EXCEPTIONS overrides the
+ BSTRLIB_DOESNT_THROW_EXCEPTIONS macro.
+
+Note that these macros must be defined consistently throughout all modules
+that use CBStrings including bstrwrap.cpp.
+
+Some older C compilers do not support functions such as vsnprintf. This is
+handled by the following macro variables:
+
+BSTRLIB_NOVSNP
+
+ - defining this indicates that the compiler does not support vsnprintf.
+ This will cause bformat and bformata to not be declared. Note that
+ for some compilers, such as Turbo C, this is set automatically.
+ Defining BSTRLIB_NOVSNP overrides the BSTRLIB_VSNP_OK macro.
+
+BSTRLIB_VSNP_OK
+
+ - defining this will disable the autodetection of compilers the do not
+ support of compilers that do not support vsnprintf.
+ Defining BSTRLIB_NOVSNP overrides the BSTRLIB_VSNP_OK macro.
+
+Semantic compilation options
+----------------------------
+
+Bstrlib comes with very few compilation options for changing the semantics of
+of the library. These are described below.
+
+BSTRLIB_DONT_ASSUME_NAMESPACE
+
+ - Defining this before including bstrwrap.h will disable the automatic
+ enabling of the Bstrlib namespace for the C++ declarations.
+
+BSTRLIB_DONT_USE_VIRTUAL_DESTRUCTOR
+
+ - Defining this will make the CBString destructor non-virtual.
+
+BSTRLIB_MEMORY_DEBUG
+
+ - Defining this will cause the bstrlib modules bstrlib.c and bstrwrap.cpp
+ to invoke a #include "memdbg.h". memdbg.h has to be supplied by the user.
+
+Note that these macros must be defined consistently throughout all modules
+that use bstrings or CBStrings including bstrlib.c, bstraux.c and
+bstrwrap.cpp.

+
+The functions
+-------------
+
+ extern bstring bfromcstr (const char * str);
+
+ Take a standard C library style '\0' terminated char buffer and generate
+ a bstring with the same contents as the char buffer. If an error occurs
+ NULL is returned.
+
+ So for example:
+
+ bstring b = bfromcstr ("Hello");
+ if (!b) {
+ fprintf (stderr, "Out of memory");
+ } else {
+ puts ((char *) b->data);
+ }
+
+ ..........................................................................
+
+ extern bstring bfromcstralloc (int mlen, const char * str);
+
+ Create a bstring which contains the contents of the '\0' terminated
+ char * buffer str. The memory buffer backing the bstring is at least
+ mlen characters in length. If an error occurs NULL is returned.
+
+ So for example:
+
+ bstring b = bfromcstralloc (64, someCstr);
+ if (b) b->data[63] = 'x';
+
+ The idea is that this will set the 64th character of b to 'x' if it is at
+ least 64 characters long otherwise do nothing. And we know this is well
+ defined so long as b was successfully created, since it will have been
+ allocated with at least 64 characters.
+
+ ..........................................................................
+
+ extern bstring blk2bstr (const void * blk, int len);
+
+ Create a bstring whose contents are described by the contiguous buffer
+ pointing to by blk with a length of len bytes. Note that this function
+ creates a copy of the data in blk, rather than simply referencing it.
+ Compare with the blk2tbstr macro. If an error occurs NULL is returned.
+
+ ..........................................................................
+
+ extern char * bstr2cstr (const_bstring s, char z);
+
+ Create a '\0' terminated char buffer which contains the contents of the
+ bstring s, except that any contained '\0' characters are converted to the
+ character in z. This returned value should be freed with bcstrfree(), by
+ the caller. If an error occurs NULL is returned.
+
+ ..........................................................................
+
+ extern int bcstrfree (char * s);
+
+ Frees a C-string generated by bstr2cstr (). This is normally unnecessary
+ since it just wraps a call to free (), however, if malloc () and free ()
+ have been redefined as a macros within the bstrlib module (via macros in
+ the memdbg.h backdoor) with some difference in behaviour from the std
+ library functions, then this allows a correct way of freeing the memory
+ that allows higher level code to be independent from these macro
+ redefinitions.
+
+ ..........................................................................
+
+ extern bstring bstrcpy (const_bstring b1);
+
+ Make a copy of the passed in bstring. The copied bstring is returned if
+ there is no error, otherwise NULL is returned.
+
+ ..........................................................................
+
+ extern int bassign (bstring a, const_bstring b);
+
+ Overwrite the bstring a with the contents of bstring b. Note that the
+ bstring a must be a well defined and writable bstring. If an error
+ occurs BSTR_ERR is returned and a is not overwritten.
+
+ ..........................................................................
+
+ int bassigncstr (bstring a, const char * str);
+
+ Overwrite the string a with the contents of char * string str. Note that
+ the bstring a must be a well defined and writable bstring. If an error
+ occurs BSTR_ERR is returned and a may be partially overwritten.
+
+ ..........................................................................
+
+ int bassignblk (bstring a, const void * s, int len);
+
+ Overwrite the string a with the contents of the block (s, len). Note that
+ the bstring a must be a well defined and writable bstring. If an error
+ occurs BSTR_ERR is returned and a is not overwritten.
+
+ ..........................................................................
+
+ extern int bassignmidstr (bstring a, const_bstring b, int left, int len);
+
+ Overwrite the bstring a with the middle of contents of bstring b
+ starting from position left and running for a length len. left and
+ len are clamped to the ends of b as with the function bmidstr. Note that
+ the bstring a must be a well defined and writable bstring. If an error
+ occurs BSTR_ERR is returned and a is not overwritten.
+
+ ..........................................................................
+
+ extern bstring bmidstr (const_bstring b, int left, int len);
+
+ Create a bstring which is the substring of b starting from position left
+ and running for a length len (clamped by the end of the bstring b.) If
+ there was no error, the value of this constructed bstring is returned
+ otherwise NULL is returned.
+
+ ..........................................................................
+
+ extern int bdelete (bstring s1, int pos, int len);
+
+ Removes characters from pos to pos+len-1 and shifts the tail of the
+ bstring starting from pos+len to pos. len must be positive for this call
+ to have any effect. The section of the bstring described by (pos, len)
+ is clamped to boundaries of the bstring b. The value BSTR_OK is returned
+ if the operation is successful, otherwise BSTR_ERR is returned.
+
+ ..........................................................................
+
+ extern int bconcat (bstring b0, const_bstring b1);
+
+ Concatenate the bstring b1 to the end of bstring b0. The value BSTR_OK
+ is returned if the operation is successful, otherwise BSTR_ERR is
+ returned.
+
+ ..........................................................................
+
+ extern int bconchar (bstring b, char c);
+
+ Concatenate the character c to the end of bstring b. The value BSTR_OK
+ is returned if the operation is successful, otherwise BSTR_ERR is
+ returned.
+
+ ..........................................................................
+
+ extern int bcatcstr (bstring b, const char * s);
+
+ Concatenate the char * string s to the end of bstring b. The value
+ BSTR_OK is returned if the operation is successful, otherwise BSTR_ERR is
+ returned.
+
+ ..........................................................................
+
+ extern int bcatblk (bstring b, const void * s, int len);
+
+ Concatenate a fixed length buffer (s, len) to the end of bstring b. The
+ value BSTR_OK is returned if the operation is successful, otherwise
+ BSTR_ERR is returned.
+
+ ..........................................................................
+
+ extern int biseq (const_bstring b0, const_bstring b1);
+
+ Compare the bstring b0 and b1 for equality. If the bstrings differ, 0
+ is returned, if the bstrings are the same, 1 is returned, if there is an
+ error, -1 is returned. If the length of the bstrings are different, this
+ function has O(1) complexity. Contained '\0' characters are not treated
+ as a termination character.
+
+ Note that the semantics of biseq are not completely compatible with
+ bstrcmp because of its different treatment of the '\0' character.
+
+ ..........................................................................
+
+ extern int bisstemeqblk (const_bstring b, const void * blk, int len);
+
+ Compare beginning of bstring b0 with a block of memory of length len for
+ equality. If the beginning of b0 differs from the memory block (or if b0
+ is too short), 0 is returned, if the bstrings are the same, 1 is returned,
+ if there is an error, -1 is returned.
+
+ ..........................................................................
+
+ extern int biseqcaseless (const_bstring b0, const_bstring b1);
+
+ Compare two bstrings for equality without differentiating between case.
+ If the bstrings differ other than in case, 0 is returned, if the bstrings
+ are the same, 1 is returned, if there is an error, -1 is returned. If
+ the length of the bstrings are different, this function is O(1). '\0'
+ termination characters are not treated in any special way.
+
+ ..........................................................................
+
+ extern int bisstemeqcaselessblk (const_bstring b0, const void * blk, int len);
+
+ Compare beginning of bstring b0 with a block of memory of length len
+ without differentiating between case for equality. If the beginning of b0
+ differs from the memory block other than in case (or if b0 is too short),
+ 0 is returned, if the bstrings are the same, 1 is returned, if there is an
+ error, -1 is returned.
+
+ ..........................................................................
+
+ extern int biseqcstr (const_bstring b, const char *s);
+
+ Compare the bstring b and char * bstring s. The C string s must be '\0'
+ terminated at exactly the length of the bstring b, and the contents
+ between the two must be identical with the bstring b with no '\0'
+ characters for the two contents to be considered equal. This is
+ equivalent to the condition that their current contents will be always be
+ equal when comparing them in the same format after converting one or the
+ other. If they are equal 1 is returned, if they are unequal 0 is
+ returned and if there is a detectable error BSTR_ERR is returned.
+
+ ..........................................................................
+
+ extern int biseqcstrcaseless (const_bstring b, const char *s);
+
+ Compare the bstring b and char * string s. The C string s must be '\0'
+ terminated at exactly the length of the bstring b, and the contents
+ between the two must be identical except for case with the bstring b with
+ no '\0' characters for the two contents to be considered equal. This is
+ equivalent to the condition that their current contents will be always be
+ equal ignoring case when comparing them in the same format after
+ converting one or the other. If they are equal, except for case, 1 is
+ returned, if they are unequal regardless of case 0 is returned and if
+ there is a detectable error BSTR_ERR is returned.
+
+ ..........................................................................
+
+ extern int bstrcmp (const_bstring b0, const_bstring b1);
+
+ Compare the bstrings b0 and b1 for ordering. If there is an error,
+ SHRT_MIN is returned, otherwise a value less than or greater than zero,
+ indicating that the bstring pointed to by b0 is lexicographically less
+ than or greater than the bstring pointed to by b1 is returned. If the
+ bstring lengths are unequal but the characters up until the length of the
+ shorter are equal then a value less than, or greater than zero,
+ indicating that the bstring pointed to by b0 is shorter or longer than the
+ bstring pointed to by b1 is returned. 0 is returned if and only if the
+ two bstrings are the same. If the length of the bstrings are different,
+ this function is O(n). Like its standard C library counter part, the
+ comparison does not proceed past any '\0' termination characters
+ encountered.
+
+ The seemingly odd error return value, merely provides slightly more
+ granularity than the undefined situation given in the C library function
+ strcmp. The function otherwise behaves very much like strcmp().
+
+ Note that the semantics of bstrcmp are not completely compatible with
+ biseq because of its different treatment of the '\0' termination
+ character.
+
+ ..........................................................................
+
+ extern int bstrncmp (const_bstring b0, const_bstring b1, int n);
+
+ Compare the bstrings b0 and b1 for ordering for at most n characters. If
+ there is an error, SHRT_MIN is returned, otherwise a value is returned as
+ if b0 and b1 were first truncated to at most n characters then bstrcmp
+ was called with these new bstrings are paremeters. If the length of the
+ bstrings are different, this function is O(n). Like its standard C
+ library counter part, the comparison does not proceed past any '\0'
+ termination characters encountered.
+
+ The seemingly odd error return value, merely provides slightly more
+ granularity than the undefined situation given in the C library function
+ strncmp. The function otherwise behaves very much like strncmp().
+
+ ..........................................................................
+
+ extern int bstricmp (const_bstring b0, const_bstring b1);
+
+ Compare two bstrings without differentiating between case. The return
+ value is the difference of the values of the characters where the two
+ bstrings first differ, otherwise 0 is returned indicating that the
+ bstrings are equal. If the lengths are different, then a difference from
+ 0 is given, but if the first extra character is '\0', then it is taken to
+ be the value UCHAR_MAX+1.
+
+ ..........................................................................
+
+ extern int bstrnicmp (const_bstring b0, const_bstring b1, int n);
+
+ Compare two bstrings without differentiating between case for at most n
+ characters. If the position where the two bstrings first differ is
+ before the nth position, the return value is the difference of the values
+ of the characters, otherwise 0 is returned. If the lengths are different
+ and less than n characters, then a difference from 0 is given, but if the
+ first extra character is '\0', then it is taken to be the value
+ UCHAR_MAX+1.
+
+ ..........................................................................
+
+ extern int bdestroy (bstring b);
+
+ Deallocate the bstring passed. Passing NULL in as a parameter will have
+ no effect. Note that both the header and the data portion of the bstring
+ will be freed. No other bstring function which modifies one of its
+ parameters will free or reallocate the header. Because of this, in
+ general, bdestroy cannot be called on any declared struct tagbstring even
+ if it is not write protected. A bstring which is write protected cannot
+ be destroyed via the bdestroy call. Any attempt to do so will result in
+ no action taken, and BSTR_ERR will be returned.
+
+ Note to C++ users: Passing in a CBString cast to a bstring will lead to
+ undefined behavior (free will be called on the header, rather than the
+ CBString destructor.) Instead just use the ordinary C++ language
+ facilities to dealloc a CBString.
+
+ ..........................................................................
+
+ extern int binstr (const_bstring s1, int pos, const_bstring s2);
+
+ Search for the bstring s2 in s1 starting at position pos and looking in a
+ forward (increasing) direction. If it is found then it returns with the
+ first position after pos where it is found, otherwise it returns BSTR_ERR.
+ The algorithm used is brute force; O(m*n).
+
+ ..........................................................................
+
+ extern int binstrr (const_bstring s1, int pos, const_bstring s2);
+
+ Search for the bstring s2 in s1 starting at position pos and looking in a
+ backward (decreasing) direction. If it is found then it returns with the
+ first position after pos where it is found, otherwise return BSTR_ERR.
+ Note that the current position at pos is tested as well -- so to be
+ disjoint from a previous forward search it is recommended that the
+ position be backed up (decremented) by one position. The algorithm used
+ is brute force; O(m*n).
+
+ ..........................................................................
+
+ extern int binstrcaseless (const_bstring s1, int pos, const_bstring s2);
+
+ Search for the bstring s2 in s1 starting at position pos and looking in a

+ found then it returns with the first position after pos where it is
+ found, otherwise it returns BSTR_ERR. The algorithm used is brute force;
+ O(m*n).
+

+
+ Search for the first position in b0 starting from pos or after, in which

+ time of O(b0->slen + b1->slen). If such a position does not exist in b0,

+ the O(log(INT_MAX)) times). This function will return with BSTR_ERR if b
+ is not detected as a valid bstring or length is not greater than 0,
+ otherwise BSTR_OK is returned.
+
+ So for example:
+
+ if (BSTR_OK == ballocmin (b, 64)) b->data[63] = 'x';
+
+ The idea is that this will set the 64th character of b to 'x' if it is at

+
+ struct tagbstring var = bsStatic ("...");
+
+ The bsStatic macro allows for static declarations of literal string
+ constants as struct tagbstring structures. The resulting tagbstring does
+ not need to be freed or destroyed. Note that this macro is only well
+ defined for string literal arguments. For more general string pointers,
+ use the btfromcstr macro.
+
+ The resulting struct tagbstring is permanently write protected. Attempts

+ (i.e., blk2bstr, bcatblk, blk2tbstr, bisstemeqblk, bisstemeqcaselessblk.)
+ Note that this macro is only well defined for string literal arguments.
+
+ Examples:

+ bstring b = blk2bstr (bsStaticBlkParms ("Fast init. "));
+ bcatblk (b, bsStaticBlkParms ("No frills fast concatenation."));
+
+ These are faster than using bfromcstr() and bcatcstr() respectively
+ because the length of the inline string is known as a compile time
+ constant. Also note that seperate struct tagbstring declarations for
+ holding the output of a bsStatic() macro are not required.

+===============================================================================
+
+The bstest module
+-----------------
+
+The bstest module is just a unit test for the bstrlib module. For correct
+implementations of bstrlib, it should execute with 0 failures being reported.
+This test should be utilized if modifications/customizations to bstrlib have
+been performed. It tests each core bstrlib function with bstrings of every
+mode (read-only, NULL, static and mutable) and ensures that the expected
+semantics are observed (including results that should indicate an error). It
+also tests for aliasing support. Passing bstest is a necessary but not a
+sufficient condition for ensuring the correctness of the bstrlib module.
+
+
+The test module
+---------------
+
+The test module is just a unit test for the bstrwrap module. For correct
+implementations of bstrwrap, it should execute with 0 failures being
+reported. This test should be utilized if modifications/customizations to
+bstrwrap have been performed. It tests each core bstrwrap function with
+CBStrings write protected or not and ensures that the expected semantics are
+observed (including expected exceptions.) Note that exceptions cannot be
+disabled to run this test. Passing test is a necessary but not a sufficient
+condition for ensuring the correctness of the bstrwrap module.
+
+===============================================================================
+
+Using Bstring and CBString as an alternative to the C library
+-------------------------------------------------------------
+
+First let us give a table of C library functions and the alternative bstring
+functions and CBString methods that should be used instead of them.
+
+C-library Bstring alternative CBString alternative
+--------- ------------------- --------------------
+gets bgets ::gets
+strcpy bassign = operator
+strncpy bassignmidstr ::midstr
+strcat bconcat += operator
+strncat bconcat + btrunc += operator + ::trunc
+strtok bsplit, bsplits ::split
+sprintf b(assign)format ::format
+snprintf b(assign)format + btrunc ::format + ::trunc
+vsprintf bvformata bvformata
+
+vsnprintf bvformata + btrunc bvformata + btrunc
+vfprintf bvformata + fputs use bvformata + fputs
+strcmp biseq, bstrcmp comparison operators.
+strncmp bstrncmp, memcmp bstrncmp, memcmp
+strlen ->slen, blength ::length
+strdup bstrcpy constructor
+strset bpattern ::fill
+strstr binstr ::find
+strpbrk binchr ::findchr
+stricmp bstricmp cast & use bstricmp
+strlwr btolower cast & use btolower
+strupr btoupper cast & use btoupper
+strrev bReverse (aux module) cast & use bReverse
+strchr bstrchr cast & use bstrchr
+strspnp use strspn use strspn
+ungetc bsunread bsunread
+
+The top 9 C functions listed here are troublesome in that they impose memory
+management in the calling function. The Bstring and CBstring interfaces have
+built-in memory management, so there is far less code with far less potential
+for buffer overrun problems. strtok can only be reliably called as a "leaf"
+calculation, since it (quite bizarrely) maintains hidden internal state. And
+gets is well known to be broken no matter what. The Bstrlib alternatives do
+not suffer from those sorts of problems.
+
+The substitute for strncat can be performed with higher performance by using
+the blk2tbstr macro to create a presized second operand for bconcat.
+
+C-library Bstring alternative CBString alternative
+--------- ------------------- --------------------
+strspn strspn acceptable strspn acceptable
+strcspn strcspn acceptable strcspn acceptable
+strnset strnset acceptable strnset acceptable
+printf printf acceptable printf acceptable
+puts puts acceptable puts acceptable
+fprintf fprintf acceptable fprintf acceptable
+fputs fputs acceptable fputs acceptable
+memcmp memcmp acceptable memcmp acceptable
+
+Remember that Bstring (and CBstring) functions will automatically append the
+'\0' character to the character data buffer. So by simply accessing the data
+buffer directly, ordinary C string library functions can be called directly
+on them. Note that bstrcmp is not the same as memcmp in exactly the same way
+that strcmp is not the same as memcmp.
+
+C-library Bstring alternative CBString alternative
+--------- ------------------- --------------------
+fread balloc + fread ::alloc + fread
+fgets balloc + fgets ::alloc + fgets
+
+These are odd ones because of the exact sizing of the buffer required. The
+Bstring and CBString alternatives requires that the buffers are forced to
+hold at least the prescribed length, then just use fread or fgets directly.
+However, typically the automatic memory management of Bstring and CBstring
+will make the typical use of fgets and fread to read specifically sized
+strings unnecessary.
+
+Implementation Choices
+----------------------
+
+Overhead:
+.........
+
+The bstring library has more overhead versus straight char buffers for most
+functions. This overhead is essentially just the memory management and
+string header allocation. This overhead usually only shows up for small
+string manipulations. The performance loss has to be considered in
+light of the following:
+
+1) What would be the performance loss of trying to write this management
+ code in one's own application?
+2) Since the bstring library source code is given, a sufficiently powerful
+ modern inlining globally optimizing compiler can remove function call
+ overhead.
+
+Since the data type is exposed, a developer can replace any unsatisfactory
+function with their own inline implementation. And that is besides the main
+point of what the better string library is mainly meant to provide. Any
+overhead lost has to be compared against the value of the safe abstraction
+for coupling memory management and string functionality.
+
+Performance of the C interface:
+...............................
+
+The algorithms used have performance advantages versus the analogous C
+library functions. For example:
+
+1. bfromcstr/blk2str/bstrcpy versus strcpy/strdup. By using memmove instead
+ of strcpy, the break condition of the copy loop is based on an independent
+ counter (that should be allocated in a register) rather than having to
+ check the results of the load. Modern out-of-order executing CPUs can
+ parallelize the final branch mis-predict penality with the loading of the
+ source string. Some CPUs will also tend to have better built-in hardware
+ support for counted memory moves than load-compare-store. (This is a
+ minor, but non-zero gain.)
+2. biseq versus strcmp. If the strings are unequal in length, bsiseq will
+ return in O(1) time. If the strings are aliased, or have aliased data
+ buffers, biseq will return in O(1) time. strcmp will always be O(k),
+ where k is the length of the common prefix or the whole string if they are
+ identical.
+3. ->slen versus strlen. ->slen is obviously always O(1), while strlen is
+ always O(n) where n is the length of the string.
+4. bconcat versus strcat. Both rely on precomputing the length of the
+ destination string argument, which will favor the bstring library. On
+ iterated concatenations the performance difference can be enormous.
+5. bsreadln versus fgets. The bsreadln function reads large blocks at a time
+ from the given stream, then parses out lines from the buffers directly.
+ Some C libraries will implement fgets as a loop over single fgetc calls.
+ Testing indicates that the bsreadln approach can be several times faster
+ for fast stream devices (such as a file that has been entirely cached.)
+6. bsplits/bsplitscb versus strspn. Accelerators for the set of match
+ characters are generated only once.
+7. binstr versus strstr. The binstr implementation unrolls the loops to
+ help reduce loop overhead. This will matter if the target string is
+ long and source string is not found very early in the target string.
+ With strstr, while it is possible to unroll the source contents, it is
+ not possible to do so with the destination contents in a way that is
+ effective because every destination character must be tested against
+ '\0' before proceeding to the next character.
+8. bReverse versus strrev. The C function must find the end of the string
+ first before swaping character pairs.
+9. bstrrchr versus no comparable C function. Its not hard to write some C
+ code to search for a character from the end going backwards. But there
+ is no way to do this without computing the length of the string with
+ strlen.
+
+Practical testing indicates that in general Bstrlib is never signifcantly
+slower than the C library for common operations, while very often having a
+performance advantage that ranges from significant to massive. Even for
+functions like b(n)inchr versus str(c)spn() (where, in theory, there is no
+advantage for the Bstrlib architecture) the performance of Bstrlib is vastly
+superior to most tested C library implementations.
+
+Some of Bstrlib's extra functionality also lead to inevitable performance
+advantages over typical C solutions. For example, using the blk2tbstr macro,
+one can (in O(1) time) generate an internal substring by reference while not
+disturbing the original string. If disturbing the original string is not an
+option, typically, a comparable char * solution would have to make a copy of
+the substring to provide similar functionality. Another example is reverse
+character set scanning -- the str(c)spn functions only scan in a forward
+direction which can complicate some parsing algorithms.
+
+Where high performance char * based algorithms are available, Bstrlib can
+still leverage them by accessing the ->data field on bstrings. So
+realistically Bstrlib can never be significantly slower than any standard
+'\0' terminated char * based solutions.
+
+Performance of the C++ interface:
+.................................
+
+The C++ interface has been designed with an emphasis on abstraction and safety
+first. However, since it is substantially a wrapper for the C bstring
+functions, for longer strings the performance comments described in the
+"Performance of the C interface" section above still apply. Note that the
+(CBString *) type can be directly cast to a (bstring) type, and passed as
+parameters to the C functions (though a CBString must never be passed to
+bdestroy.)
+
+Probably the most controversial choice is performing full bounds checking on
+the [] operator. This decision was made because 1) the fast alternative of
+not bounds checking is still available by first casting the CBString to a
+(const char *) buffer or to a (struct tagbstring) then derefencing .data and
+2) because the lack of bounds checking is seen as one of the main weaknesses
+of C/C++ versus other languages. This check being done on every access leads
+to individual character extraction being actually slower than other languages
+in this one respect (other language's compilers will normally dedicate more
+resources on hoisting or removing bounds checking as necessary) but otherwise
+bring C++ up to the level of other languages in terms of functionality.
+
+It is common for other C++ libraries to leverage the abstractions provided by
+C++ to use reference counting and "copy on write" policies. While these
+techniques can speed up some scenarios, they impose a problem with respect to
+thread safety. bstrings and CBStrings can be properly protected with
+"per-object" mutexes, meaning that two bstrlib calls can be made and execute
+simultaneously, so long as the bstrings and CBstrings are distinct. With a
+reference count and alias before copy on write policy, global mutexes are
+required that prevent multiple calls to the strings library to execute
+simultaneously regardless of whether or not the strings represent the same
+string.
+
+One interesting trade off in CBString is that the default constructor is not
+trivial. I.e., it always prepares a ready to use memory buffer. The purpose
+is to ensure that there is a uniform internal composition for any functioning
+CBString that is compatible with bstrings. It also means that the other
+methods in the class are not forced to perform "late initialization" checks.
+In the end it means that construction of CBStrings are slower than other
+comparable C++ string classes. Initial testing, however, indicates that
+CBString outperforms std::string and MFC's CString, for example, in all other
+operations. So to work around this weakness it is recommended that CBString
+declarations be pushed outside of inner loops.
+
+Practical testing indicates that with the exception of the caveats given
+above (constructors and safe index character manipulations) the C++ API for
+Bstrlib generally outperforms popular standard C++ string classes. Amongst
+the standard libraries and compilers, the quality of concatenation operations
+varies wildly and very little care has gone into search functions. Bstrlib
+dominates those performance benchmarks.
+
+Memory management:
+..................
+
+The bstring functions which write and modify bstrings will automatically
+reallocate the backing memory for the char buffer whenever it is required to
+grow. The algorithm for resizing chosen is to snap up to sizes that are a
+power of two which are sufficient to hold the intended new size. Memory
+reallocation is not performed when the required size of the buffer is
+decreased. This behavior can be relied on, and is necessary to make the
+behaviour of balloc deterministic. This trades off additional memory usage
+for decreasing the frequency for required reallocations:
+
+1. For any bstring whose size never exceeds n, its buffer is not ever
+ reallocated more than log_2(n) times for its lifetime.
+2. For any bstring whose size never exceeds n, its buffer is never more than
+ 2*(n+1) in length. (The extra characters beyond 2*n are to allow for the
+ implicit '\0' which is always added by the bstring modifying functions.)
+
+Decreasing the buffer size when the string decreases in size would violate 1)
+above and in real world case lead to pathological heap thrashing. Similarly,
+allocating more tightly than "least power of 2 greater than necessary" would
+lead to a violation of 1) and have the same potential for heap thrashing.
+
+Property 2) needs emphasizing. Although the memory allocated is always a
+power of 2, for a bstring that grows linearly in size, its buffer memory also
+grows linearly, not exponentially. The reason is that the amount of extra
+space increases with each reallocation, which decreases the frequency of
+future reallocations.
+
+Obviously, given that bstring writing functions may reallocate the data
+buffer backing the target bstring, one should not attempt to cache the data
+buffer address and use it after such bstring functions have been called.
+This includes making reference struct tagbstrings which alias to a writable
+bstring.
+
+balloc or bfromcstralloc can be used to preallocate the minimum amount of
+space used for a given bstring. This will reduce even further the number of
+times the data portion is reallocated. If the length of the string is never
+more than one less than the memory length then there will be no further
+reallocations.
+
+Note that invoking the bwriteallow macro may increase the number of reallocs
+by one more than necessary for every call to bwriteallow interleaved with any
+bstring API which writes to this bstring.
+
+The library does not use any mechanism for automatic clean up for the C API.
+Thus explicit clean up via calls to bdestroy() are required to avoid memory
+leaks.
+
+Constant and static tagbstrings:
+................................
+
+A struct tagbstring can be write protected from any bstrlib function using
+the bwriteprotect macro. A write protected struct tagbstring can then be
+reset to being writable via the bwriteallow macro. There is, of course, no
+protection from attempts to directly access the bstring members. Modifying a
+bstring which is write protected by direct access has undefined behavior.
+
+static struct tagbstrings can be declared via the bsStatic macro. They are
+considered permanently unwritable. Such struct tagbstrings's are declared
+such that attempts to write to it are not well defined. Invoking either
+bwriteallow or bwriteprotect on static struct tagbstrings has no effect.
+
+struct tagbstring's initialized via btfromcstr or blk2tbstr are protected by
+default but can be made writeable via the bwriteallow macro. If bwriteallow
+is called on such struct tagbstring's, it is the programmer's responsibility
+to ensure that:
+
+1) the buffer supplied was allocated from the heap.
+2) bdestroy is not called on this tagbstring (unless the header itself has
+ also been allocated from the heap.)
+3) free is called on the buffer to reclaim its memory.
+
+bwriteallow and bwriteprotect can be invoked on ordinary bstrings (they have
+to be dereferenced with the (*) operator to get the levels of indirection
+correct) to give them write protection.
+
+Buffer declaration:
+...................
+
+The memory buffer is actually declared "unsigned char *" instead of "char *".
+The reason for this is to trigger compiler warnings whenever uncasted char
+buffers are assigned to the data portion of a bstring. This will draw more
+diligent programmers into taking a second look at the code where they
+have carelessly left off the typically required cast. (Research from
+AT&T/Lucent indicates that additional programmer eyeballs is one of the most
+effective mechanisms at ferreting out bugs.)
+
+Function pointers:
+..................
+
+The bgets, bread and bStream functions use function pointers to obtain
+strings from data streams. The function pointer declarations have been
+specifically chosen to be compatible with the fgetc and fread functions.
+While this may seem to be a convoluted way of implementing fgets and fread
+style functionality, it has been specifically designed this way to ensure
+that there is no dependency on a single narrowly defined set of device
+interfaces, such as just stream I/O. In the embedded world, its quite
+possible to have environments where such interfaces may not exist in the
+standard C library form. Furthermore, the generalization that this opens up
+allows for more sophisticated uses for these functions (performing an fgets
+like function on a socket, for example.) By using function pointers, it also
+allows such abstract stream interfaces to be created using the bstring library
+itself while not creating a circular dependency.
+
+Use of int's for sizes:
+.......................
+
+This is just a recognition that 16bit platforms with requirements for strings
+that are larger than 64K and 32bit+ platforms with requirements for strings
+that are larger than 4GB are pretty marginal. The main focus is for 32bit
+platforms, and emerging 64bit platforms with reasonable < 4GB string
+requirements. Using ints allows for negative values which has meaning
+internally to bstrlib.
+
+Semantic consideration:
+.......................
+
+Certain care needs to be taken when copying and aliasing bstrings. A bstring
+is essentially a pointer type which points to a multipart abstract data
+structure. Thus usage, and lifetime of bstrings have semantics that follow
+these considerations. For example:
+
+ bstring a, b;
+ struct tagbstring t;
+
+ a = bfromcstr("Hello"); /* Create new bstring and copy "Hello" into it. */
+ b = a; /* Alias b to the contents of a. */
+ t = *a; /* Create a current instance pseudo-alias of a. */
+ bconcat (a, b); /* Double a and b, t is now undefined. */
+ bdestroy (a); /* Destroy the contents of both a and b. */
+
+Variables of type bstring are really just references that point to real
+bstring objects. The equal operator (=) creates aliases, and the asterisk
+dereference operator (*) creates a kind of alias to the current instance (which
+is generally not useful for any purpose.) Using bstrcpy() is the correct way
+of creating duplicate instances. The ampersand operator (&) is useful for
+creating aliases to struct tagbstrings (remembering that constructed struct
+tagbstrings are not writable by default.)
+
+CBStrings use complete copy semantics for the equal operator (=), and thus do
+not have these sorts of issues.
+
+Debugging:
+..........
+
+Bstrings have a simple, exposed definition and construction, and the library
+itself is open source. So most debugging is going to be fairly straight-
+forward. But the memory for bstrings come from the heap, which can often be
+corrupted indirectly, and it might not be obvious what has happened even from
+direct examination of the contents in a debugger or a core dump. There are
+some tools such as Purify, Insure++ and Electric Fence which can help solve
+such problems, however another common approach is to directly instrument the
+calls to malloc, realloc, calloc, free, memcpy, memmove and/or other calls
+by overriding them with macro definitions.
+
+Although the user could hack on the Bstrlib sources directly as necessary to
+perform such an instrumentation, Bstrlib comes with a built-in mechanism for
+doing this. By defining the macro BSTRLIB_MEMORY_DEBUG and providing an
+include file named memdbg.h this will force the core Bstrlib modules to
+attempt to include this file. In such a file, macros could be defined which
+overrides Bstrlib's useage of the C standard library.
+
+Rather than calling malloc, realloc, free, memcpy or memmove directly, Bstrlib
+emits the macros bstr__alloc, bstr__realloc, bstr__free, bstr__memcpy and
+bstr__memmove in their place respectively. By default these macros are simply
+assigned to be equivalent to their corresponding C standard library function
+call. However, if they are given earlier macro definitions (via the back
+door include file) they will not be given their default definition. In this
+way Bstrlib's interface to the standard library can be changed but without
+having to directly redefine or link standard library symbols (both of which
+are not strictly ANSI C compliant.)
+
+An example definition might include:
+
+ #define bstr__alloc(sz) X_malloc ((sz), __LINE__, __FILE__)
+
+which might help contextualize heap entries in a debugging environment.
+
+The NULL parameter and sanity checking of bstrings is part of the Bstrlib
+API, and thus Bstrlib itself does not present any different modes which would
+correspond to "Debug" or "Release" modes. Bstrlib always contains mechanisms
+which one might think of as debugging features, but retains the performance
+and small memory footprint one would normally associate with release mode
+code.
+
+Integration Microsoft's Visual Studio debugger:
+...............................................
+
+Microsoft's Visual Studio debugger has a capability of customizable mouse
+float over data type descriptions. This is accomplished by editting the
+AUTOEXP.DAT file to include the following:
+
+ ; new for CBString
+ tagbstring =slen=<slen> mlen=<mlen> <data,st>
+ Bstrlib::CBStringList =count=<size()>
+
+In Visual C++ 6.0 this file is located in the directory:
+
+ C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin
+
+and in Visual Studio .NET 2003 its located here:
+
+ C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Packages\Debugger
+
+This will improve the ability of debugging with Bstrlib under Visual Studio.
+
+Security
+--------
+
+Bstrlib does not come with explicit security features outside of its fairly
+comprehensive error detection, coupled with its strict semantic support.
+That is to say that certain common security problems, such as buffer overrun,
+constant overwrite, arbitrary truncation etc, are far less likely to happen
+inadvertently. Where it does help, Bstrlib maximizes its advantage by
+providing developers a simple adoption path that lets them leave less secure
+string mechanisms behind. The library will not leave developers wanting, so
+they will be less likely to add new code using a less secure string library
+to add functionality that might be missing from Bstrlib.
+
+That said there are a number of security ideas not addressed by Bstrlib:
+
+1. Race condition exploitation (i.e., verifying a string's contents, then
+raising the privilege level and execute it as a shell command as two
+non-atomic steps) is well beyond the scope of what Bstrlib can provide. It
+should be noted that MFC's built-in string mutex actually does not solve this
+problem either -- it just removes immediate data corruption as a possible
+outcome of such exploit attempts (it can be argued that this is worse, since
+it will leave no trace of the exploitation). In general race conditions have
+to be dealt with by careful design and implementation; it cannot be assisted
+by a string library.
+
+2. Any kind of access control or security attributes to prevent usage in
+dangerous interfaces such as system(). Perl includes a "trust" attribute
+which can be endowed upon strings that are intended to be passed to such
+dangerous interfaces. However, Perl's solution reflects its own limitations
+-- notably that it is not a strongly typed language. In the example code for
+Bstrlib, there is a module called taint.cpp. It demonstrates how to write a
+simple wrapper class for managing "untainted" or trusted strings using the
+type system to prevent questionable mixing of ordinary untrusted strings with
+untainted ones then passing them to dangerous interfaces. In this way the
+security correctness of the code reduces to auditing the direct usages of
+dangerous interfaces or promotions of tainted strings to untainted ones.
+
+3. Encryption of string contents is way beyond the scope of Bstrlib.
+Maintaining encrypted string contents in the futile hopes of thwarting things
+like using system-level debuggers to examine sensitive string data is likely
+to be a wasted effort (imagine a debugger that runs at a higher level than a
+virtual processor where the application runs). For more standard encryption
+usages, since the bstring contents are simply binary blocks of data, this
+should pose no problem for usage with other standard encryption libraries.
+
+Compatibility
+-------------
+
+The Better String Library is known to compile and function correctly with the
+following compilers:
+
+ - Microsoft Visual C++
+ - Watcom C/C++
+ - Intel's C/C++ compiler (Windows)
+ - The GNU C/C++ compiler (cygwin and Linux on PPC64)
+ - Borland C
+ - Turbo C
+
+Setting of configuration options should be unnecessary for these compilers
+(unless exceptions are being disabled or STLport has been added to WATCOM
+C/C++). Bstrlib has been developed with an emphasis on portability. As such
+porting it to other compilers should be straight forward. This package
+includes a porting guide (called porting.txt) which explains what issues may
+exist for porting Bstrlib to different compilers and environments.
+
+ANSI issues
+-----------
+
+1. The function pointer types bNgetc and bNread have prototypes which are very
+similar to, but not exactly the same as fgetc and fread respectively.
+Basically the FILE * parameter is replaced by void *. The purpose of this
+was to allow one to create other functions with fgetc and fread like
+semantics without being tied to ANSI C's file streaming mechanism. I.e., one
+could very easily adapt it to sockets, or simply reading a block of memory,
+or procedurally generated strings (for fractal generation, for example.)
+
+The problem is that invoking the functions (bNgetc)fgetc and (bNread)fread is
+not technically legal in ANSI C. The reason being that the compiler is only
+able to coerce the function pointers themselves into the target type, however
+are unable to perform any cast (implicit or otherwise) on the parameters
+passed once invoked. I.e., if internally void * and FILE * need some kind of
+mechanical coercion, the compiler will not properly perform this conversion
+and thus lead to undefined behavior.
+
+Apparently a platform from Data General called "Eclipse" and another from
+Tandem called "NonStop" have a different representation for pointers to bytes
+and pointers to words, for example, where coercion via casting is necessary.
+(Actual confirmation of the existence of such machines is hard to come by, so
+it is prudent to be skeptical about this information.) However, this is not
+an issue for any known contemporary platforms. One may conclude that such
+platforms are effectively apocryphal even if they do exist.
+
+To correctly work around this problem to the satisfaction of the ANSI
+limitations, one needs to create wrapper functions for fgets and/or
+fread with the prototypes of bNgetc and/or bNread respectively which performs
+no other action other than to explicitely cast the void * parameter to a
+FILE *, and simply pass the remaining parameters straight to the function
+pointer call.
+
+The wrappers themselves are trivial:
+
+ size_t freadWrap (void * buff, size_t esz, size_t eqty, void * parm) {
+ return fread (buff, esz, eqty, (FILE *) parm);
+ }
+
+ int fgetcWrap (void * parm) {
+ return fgetc ((FILE *) parm);
+ }
+
+These have not been supplied in bstrlib or bstraux to prevent unnecessary
+linking with file I/O functions.
+
+2. vsnprintf is not available on all compilers. Because of this, the bformat
+and bformata functions (and format and formata methods) are not guaranteed to
+work properly. For those compilers that don't have vsnprintf, the
+BSTRLIB_NOVSNP macro should be set before compiling bstrlib, and the format
+functions/method will be disabled.
+
+The more recent ANSI C standards have specified the required inclusion of a
+vsnprintf function.
+
+3. The bstrlib function names are not unique in the first 6 characters. This
+is only an issue for older C compiler environments which do not store more
+than 6 characters for function names.
+
+4. The bsafe module defines macros and function names which are part of the
+C library. This simply overrides the definition as expected on all platforms
+tested, however it is not sanctioned by the ANSI standard. This module is
+clearly optional and should be omitted on platforms which disallow its
+undefined semantics.
+
+In practice the real issue is that some compilers in some modes of operation
+can/will inline these standard library functions on a module by module basis
+as they appear in each. The linker will thus have no opportunity to override
+the implementation of these functions for those cases. This can lead to
+inconsistent behaviour of the bsafe module on different platforms and
+compilers.
+
+===============================================================================
+
+Comparison with Microsoft's CString class
+-----------------------------------------
+
+Although developed independently, CBStrings have very similar functionality to
+Microsoft's CString class. However, the bstring library has significant
+advantages over CString:
+
+1. Bstrlib is a C-library as well as a C++ library (using the C++ wrapper).
+
+ - Thus it is compatible with more programming environments and
+ available to a wider population of programmers.
+
+2. The internal structure of a bstring is considered exposed.
+
+ - A single contiguous block of data can be cut into read-only pieces by
+ simply creating headers, without allocating additional memory to create
+ reference copies of each of these sub-strings.
+ - In this way, using bstrings in a totally abstracted way becomes a choice
+ rather than an imposition. Further this choice can be made differently
+ at different layers of applications that use it.
+
+3. Static declaration support precludes the need for constructor
+ invocation.
+
+ - Allows for static declarations of constant strings that has no
+ additional constructor overhead.
+
+4. Bstrlib is not attached to another library.
+
+ - Bstrlib is designed to be easily plugged into any other library
+ collection, without dependencies on other libraries or paradigms (such
+ as "MFC".)
+
+The bstring library also comes with a few additional functions that are not
+available in the CString class:
+
+ - bsetstr
+ - bsplit
+ - bread
+ - breplace (this is different from CString::Replace())
+ - Writable indexed characters (for example a[i]='x')
+
+Interestingly, although Microsoft did implement mid$(), left$() and right$()
+functional analogues (these are functions from GWBASIC) they seem to have
+forgotten that mid$() could be also used to write into the middle of a string.
+This functionality exists in Bstrlib with the bsetstr() and breplace()
+functions.
+
+Among the disadvantages of Bstrlib is that there is no special support for
+localization or wide characters. Such things are considered beyond the scope
+of what bstrings are trying to deliver. CString essentially supports the
+older UCS-2 version of Unicode via widechar_t as an application-wide compile
+time switch.
+
+CString's also use built-in mechanisms for ensuring thread safety under all
+situations. While this makes writing thread safe code that much easier, this
+built-in safety feature has a price -- the inner loops of each CString method
+runs in its own critical section (grabbing and releasing a light weight mutex
+on every operation.) The usual way to decrease the impact of a critical
+section performance penalty is to amortize more operations per critical
+section. But since the implementation of CStrings is fixed as a one critical
+section per-operation cost, there is no way to leverage this common
+performance enhancing idea.
+
+The search facilities in Bstrlib are comparable to those in MFC's CString
+class, though it is missing locale specific collation. But because Bstrlib
+is interoperable with C's char buffers, it will allow programmers to write
+their own string searching mechanism (such as Boyer-Moore), or be able to
+choose from a variety of available existing string searching libraries (such
+as those for regular expressions) without difficulty.
+
+Microsoft used a very non-ANSI conforming trick in its implementation to
+allow printf() to use the "%s" specifier to output a CString correctly. This
+can be convenient, but it is inherently not portable. CBString requires an
+explicit cast, while bstring requires the data member to be dereferenced.
+Microsoft's own documentation recommends casting, instead of relying on this
+feature.
+
+Comparison with C++'s std::string
+---------------------------------
+
+This is the C++ language's standard STL based string class.
+
+1. There is no C implementation.
+2. The [] operator is not bounds checked.
+3. Missing a lot of useful functions like printf-like formatting.
+4. Some sub-standard std::string implementations (SGI) are necessarily unsafe
+ to use with multithreading.
+5. Limited by STL's std::iostream which in turn is limited by ifstream which
+ can only take input from files. (Compare to CBStream's API which can take
+ abstracted input.)
+6. Extremely uneven performance across implementations.
+
+Comparison with ISO C TR 24731 proposal
+---------------------------------------
+
+Following the ISO C99 standard, Microsoft has proposed a group of C library
+extensions which are supposedly "safer and more secure". This proposal is
+expected to be adopted by the ISO C standard which follows C99.
+
+The proposal reveals itself to be very similar to Microsoft's "StrSafe"
+library. The functions are basically the same as other standard C library
+string functions except that destination parameters are paired with an
+additional length parameter of type rsize_t. rsize_t is the same as size_t,
+however, the range is checked to make sure its between 1 and RSIZE_MAX. Like
+Bstrlib, the functions perform a "parameter check". Unlike Bstrlib, when a
+parameter check fails, rather than simply outputing accumulatable error
+statuses, they call a user settable global error function handler, and upon
+return of control performs no (additional) detrimental action. The proposal
+covers basic string functions as well as a few non-reenterable functions
+(asctime, ctime, and strtok).
+
+1. Still based solely on char * buffers (and therefore strlen() and strcat()
+ is still O(n), and there are no faster streq() comparison functions.)
+2. No growable string semantics.
+3. Requires manual buffer length synchronization in the source code.
+4. No attempt to enhance functionality of the C library.
+5. Introduces a new error scenario (strings exceeding RSIZE_MAX length).
+
+The hope is that by exposing the buffer length requirements there will be
+fewer buffer overrun errors. However, the error modes are really just
+transformed, rather than removed. The real problem of buffer overflows is
+that they all happen as a result of erroneous programming. So forcing
+programmers to manually deal with buffer limits, will make them more aware of
+the problem but doesn't remove the possibility of erroneous programming. So
+a programmer that erroneously mixes up the rsize_t parameters is no better off
+from a programmer that introduces potential buffer overflows through other
+more typical lapses. So at best this may reduce the rate of erroneous
+programming, rather than making any attempt at removing failure modes.
+
+The error handler can discriminate between types of failures, but does not
+take into account any callsite context. So the problem is that the error is
+going to be manifest in a piece of code, but there is no pointer to that
+code. It would seem that passing in the call site __FILE__, __LINE__ as
+parameters would be very useful, but the API clearly doesn't support such a
+thing (it would increase code bloat even more than the extra length
+parameter does, and would require macro tricks to implement).
+
+The Bstrlib C API takes the position that error handling needs to be done at
+the callsite, and just tries to make it as painless as possible. Furthermore,
+error modes are removed by supporting auto-growing strings and aliasing. For
+capturing errors in more central code fragments, Bstrlib's C++ API uses
+exception handling extensively, which is superior to the leaf-only error
+handler approach.
+
+Comparison with Managed String Library CERT proposal
+----------------------------------------------------
+
+The main webpage for the managed string library:
+http://www.cert.org/secure-coding/managedstring.html
+
+Robert Seacord at CERT has proposed a C string library that he calls the
+"Managed String Library" for C. Like Bstrlib, it introduces a new type
+which is called a managed string. The structure of a managed string
+(string_m) is like a struct tagbstring but missing the length field. This
+internal structure is considered opaque. The length is, like the C standard
+library, always computed on the fly by searching for a terminating NUL on
+every operation that requires it. So it suffers from every performance
+problem that the C standard library suffers from. Interoperating with C
+string APIs (like printf, fopen, or anything else that takes a string
+parameter) requires copying to additionally allocating buffers that have to
+be manually freed -- this makes this library probably slower and more
+cumbersome than any other string library in existence.
+
+The library gives a fully populated error status as the return value of every
+string function. The hope is to be able to diagnose all problems
+specifically from the return code alone. Comparing this to Bstrlib, which
+aways returns one consistent error message, might make it seem that Bstrlib
+would be harder to debug; but this is not true. With Bstrlib, if an error
+occurs there is always enough information from just knowing there was an error
+and examining the parameters to deduce exactly what kind of error has
+happened. The managed string library thus gives up nested function calls
+while achieving little benefit, while Bstrlib does not.
+
+One interesting feature that "managed strings" has is the idea of data
+sanitization via character set whitelisting. That is to say, a globally
+definable filter that makes any attempt to put invalid characters into strings
+lead to an error and not modify the string. The author gives the following
+example:
+
+ // create valid char set
+ if (retValue = strcreate_m(&str1, "abc") ) {
+ fprintf(
+ stderr,
+ "Error %d from strcreate_m.\n",
+ retValue
+ );
+ }
+ if (retValue = setcharset(str1)) {
+ fprintf(
+ stderr,
+ "Error %d from setcharset().\n",
+ retValue
+ );
+ }
+ if (retValue = strcreate_m(&str1, "aabbccabc")) {
+ fprintf(
+ stderr,
+ "Error %d from strcreate_m.\n",
+ retValue
+ );
+ }
+ // create string with invalid char set
+ if (retValue = strcreate_m(&str1, "abbccdabc")) {
+ fprintf(
+ stderr,
+ "Error %d from strcreate_m.\n",
+ retValue
+ );
+ }
+
+Which we can compare with a more Bstrlib way of doing things:
+
+ bstring bCreateWithFilter (const char * cstr, const_bstring filter) {
+ bstring b = bfromcstr (cstr);
+ if (BSTR_ERR != bninchr (b, filter) && NULL != b) {
+ fprintf (stderr, "Filter violation.\n");
+ bdestroy (b);
+ b = NULL;
+ }
+ return b;
+ }
+
+ struct tagbstring charFilter = bsStatic ("abc");
+ bstring str1 = bCreateWithFilter ("aabbccabc", &charFilter);
+ bstring str2 = bCreateWithFilter ("aabbccdabc", &charFilter);
+
+The first thing we should notice is that with the Bstrlib approach you can
+have different filters for different strings if necessary. Furthermore,
+selecting a charset filter in the Managed String Library is uni-contextual.
+That is to say, there can only be one such filter active for the entire
+program, which means its usage is not well defined for intermediate library
+usage (a library that uses it will interfere with user code that uses it, and
+vice versa.) It is also likely to be poorly defined in multi-threading
+environments.
+
+There is also a question as to whether the data sanitization filter is checked
+on every operation, or just on creation operations. Since the charset can be
+set arbitrarily at run time, it might be set *after* some managed strings have
+been created. This would seem to imply that all functions should run this
+additional check every time if there is an attempt to enforce this. This
+would make things tremendously slow. On the other hand, if it is assumed that
+only creates and other operations that take char *'s as input need be checked
+because the charset was only supposed to be called once at and before any
+other managed string was created, then one can see that its easy to cover
+Bstrlib with equivalent functionality via a few wrapper calls such as the
+example given above.
+
+And finally we have to question the value of sanitation in the first place.
+For example, for httpd servers, there is generally a requirement that the
+URLs parsed have some form that avoids undesirable translation to local file
+system filenames or resources. The problem is that the way URLs can be
+encoded, it must be completely parsed and translated to know if it is using
+certain invalid character combinations. That is to say, merely filtering
+each character one at a time is not necessarily the right way to ensure that
+a string has safe contents.
+
+In the article that describes this proposal, it is claimed that it fairly
+closely approximates the existing C API semantics. On this point we should
+compare this "closeness" with Bstrlib:
+
+ Bstrlib Managed String Library
+ ------- ----------------------
+
+Pointer arithmetic Segment arithmetic N/A
+
+Use in C Std lib ->data, or bdata{e} getstr_m(x,*) ... free(x)
+
+String literals bsStatic, bsStaticBlk strcreate_m()
+
+Transparency Complete None
+
+Its pretty clear that the semantic mapping from C strings to Bstrlib is fairly
+straightforward, and that in general semantic capabilities are the same or
+superior in Bstrlib. On the other hand the Managed String Library is either
+missing semantics or changes things fairly significantly.
+
+Comparison with Annexia's c2lib library
+---------------------------------------
+
+This library is available at:
+http://www.annexia.org/freeware/c2lib
+
+1. Still based solely on char * buffers (and therefore strlen() and strcat()
+ is still O(n), and there are no faster streq() comparison functions.)
+ Their suggestion that alternatives which wrap the string data type (such as
+ bstring does) imposes a difficulty in interoperating with the C langauge's
+ ordinary C string library is not founded.
+2. Introduction of memory (and vector?) abstractions imposes a learning
+ curve, and some kind of memory usage policy that is outside of the strings
+ themselves (and therefore must be maintained by the developer.)
+3. The API is massive, and filled with all sorts of trivial (pjoin) and
+ controvertial (pmatch -- regular expression are not sufficiently
+ standardized, and there is a very large difference in performance between
+ compiled and non-compiled, REs) functions. Bstrlib takes a decidely
+ minimal approach -- none of the functionality in c2lib is difficult or
+ challenging to implement on top of Bstrlib (except the regex stuff, which
+ is going to be difficult, and controvertial no matter what.)
+4. Understanding why c2lib is the way it is pretty much requires a working
+ knowledge of Perl. bstrlib requires only knowledge of the C string library
+ while providing just a very select few worthwhile extras.
+5. It is attached to a lot of cruft like a matrix math library (that doesn't
+ include any functions for getting the determinant, eigenvectors,
+ eigenvalues, the matrix inverse, test for singularity, test for
+ orthogonality, a grahm schmit orthogonlization, LU decomposition ... I
+ mean why bother?)
+
+Convincing a development house to use c2lib is likely quite difficult. It
+introduces too much, while not being part of any kind of standards body. The
+code must therefore be trusted, or maintained by those that use it. While
+bstring offers nothing more on this front, since its so much smaller, covers
+far less in terms of scope, and will typically improve string performance,
+the barrier to usage should be much smaller.
+
+Comparison with stralloc/qmail
+------------------------------
+
+More information about this library can be found here:
+http://www.canonical.org/~kragen/stralloc.html or here:
+http://cr.yp.to/lib/stralloc.html
+
+1. Library is very very minimal. A little too minimal.
+2. Untargetted source parameters are not declared const.
+3. Slightly different expected emphasis (like _cats function which takes an
+ ordinary C string char buffer as a parameter.) Its clear that the
+ remainder of the C string library is still required to perform more
+ useful string operations.
+
+The struct declaration for their string header is essentially the same as that
+for bstring. But its clear that this was a quickly written hack whose goals
+are clearly a subset of what Bstrlib supplies. For anyone who is served by
+stralloc, Bstrlib is complete substitute that just adds more functionality.
+
+stralloc actually uses the interesting policy that a NULL data pointer
+indicates an empty string. In this way, non-static empty strings can be
+declared without construction. This advantage is minimal, since static empty
+bstrings can be declared inline without construction, and if the string needs
+to be written to it should be constructed from an empty string (or its first
+initializer) in any event.
+
+wxString class
+--------------
+
+This is the string class used in the wxWindows project. A description of
+wxString can be found here:
+http://www.wxwindows.org/manuals/2.4.2/wx368.htm#wxstring
+
+This C++ library is similar to CBString. However, it is littered with
+trivial functions (IsAscii, UpperCase, RemoveLast etc.)
+
+1. There is no C implementation.
+2. The memory management strategy is to allocate a bounded fixed amount of
+ additional space on each resize, meaning that it does not have the
+ log_2(n) property that Bstrlib has (it will thrash very easily, cause
+ massive fragmentation in common heap implementations, and can easily be a
+ common source of performance problems).
+3. The library uses a "copy on write" strategy, meaning that it has to deal
+ with multithreading problems.
+
+Vstr
+----
+
+This is a highly orthogonal C string library with an emphasis on
+networking/realtime programming. It can be found here:
+http://www.and.org/vstr/
+
+1. The convoluted internal structure does not contain a '\0' char * compatible
+ buffer, so interoperability with the C library a non-starter.
+2. The API and implementation is very large (owing to its orthogonality) and
+ can lead to difficulty in understanding its exact functionality.
+3. An obvious dependency on gnu tools (confusing make configure step)
+4. Uses a reference counting system, meaning that it is not likely to be
+ thread safe.
+
+The implementation has an extreme emphasis on performance for nontrivial
+actions (adds, inserts and deletes are all constant or roughly O(#operations)
+time) following the "zero copy" principle. This trades off performance of
+trivial functions (character access, char buffer access/coersion, alias
+detection) which becomes significantly slower, as well as incremental
+accumulative costs for its searching/parsing functions. Whether or not Vstr
+wins any particular performance benchmark will depend a lot on the benchmark,
+but it should handily win on some, while losing dreadfully on others.
+
+The learning curve for Vstr is very steep, and it doesn't come with any
+obvious way to build for Windows or other platforms without gnu tools. At
+least one mechanism (the iterator) introduces a new undefined scenario
+(writing to a Vstr while iterating through it.) Vstr has a very large
+footprint, and is very ambitious in its total functionality. Vstr has no C++
+API.
+
+Vstr usage requires context initialization via vstr_init() which must be run
+in a thread-local context. Given the totally reference based architecture
+this means that sharing Vstrings across threads is not well defined, or at
+least not safe from race conditions. This API is clearly geared to the older
+standard of fork() style multitasking in UNIX, and is not safely transportable
+to modern shared memory multithreading available in Linux and Windows. There
+is no portable external solution making the library thread safe (since it
+requires a mutex around each Vstr context -- not each string.)
+
+In the documentation for this library, a big deal is made of its self hosted
+s(n)printf-like function. This is an issue for older compilers that don't
+include vsnprintf(), but also an issue because Vstr has a slow conversion to
+'\0' terminated char * mechanism. That is to say, using "%s" to format data
+that originates from Vstr would be slow without some sort of native function
+to do so. Bstrlib sidesteps the issue by relying on what snprintf-like
+functionality does exist and having a high performance conversion to a char *
+compatible string so that "%s" can be used directly.
+
+Str Library
+-----------
+
+This is a fairly extensive string library, that includes full unicode support
+and targetted at the goal of out performing MFC and STL. The architecture,
+similarly to MFC's CStrings, is a copy on write reference counting mechanism.
+
+http://www.utilitycode.com/str/default.aspx
+
+1. Commercial.
+2. C++ only.
+
+This library, like Vstr, uses a ref counting system. There is only so deeply
+I can analyze it, since I don't have a license for it. However, performance
+improvements over MFC's and STL, doesn't seem like a sufficient reason to
+move your source base to it. For example, in the future, Microsoft may
+improve the performance CString.
+
+It should be pointed out that performance testing of Bstrlib has indicated
+that its relative performance advantage versus MFC's CString and STL's
+std::string is at least as high as that for the Str library.
+
+libmib astrings
+---------------
+
+A handful of functional extensions to the C library that add dynamic string
+functionality.
+http://www.mibsoftware.com/libmib/astring/
+
+This package basically references strings through char ** pointers and assumes
+they are pointing to the top of an allocated heap entry (or NULL, in which
+case memory will be newly allocated from the heap.) So its still up to user
+to mix and match the older C string functions with these functions whenever
+pointer arithmetic is used (i.e., there is no leveraging of the type system
+to assert semantic differences between references and base strings as Bstrlib
+does since no new types are introduced.) Unlike Bstrlib, exact string length
+meta data is not stored, thus requiring a strlen() call on *every* string
+writing operation. The library is very small, covering only a handful of C's
+functions.
+
+While this is better than nothing, it is clearly slower than even the
+standard C library, less safe and less functional than Bstrlib.
+
+To explain the advantage of using libmib, their website shows an example of
+how dangerous C code:
+
+ char buf[256];
+ char *pszExtraPath = ";/usr/local/bin";
+
+ strcpy(buf,getenv("PATH")); /* oops! could overrun! */
+ strcat(buf,pszExtraPath); /* Could overrun as well! */
+
+ printf("Checking...%s\n",buf); /* Some printfs overrun too! */
+
+is avoided using libmib:
+
+ char *pasz = 0; /* Must initialize to 0 */
+ char *paszOut = 0;
+ char *pszExtraPath = ";/usr/local/bin";
+
+ if (!astrcpy(&pasz,getenv("PATH"))) /* malloc error */ exit(-1);
+ if (!astrcat(&pasz,pszExtraPath)) /* malloc error */ exit(-1);
+
+ /* Finally, a "limitless" printf! we can use */
+ asprintf(&paszOut,"Checking...%s\n",pasz);fputs(paszOut,stdout);
+
+ astrfree(&pasz); /* Can use free(pasz) also. */
+ astrfree(&paszOut);
+
+However, compare this to Bstrlib:
+
+ bstring b, out;
+
+ bcatcstr (b = bfromcstr (getenv ("PATH")), ";/usr/local/bin");
+ out = bformat ("Checking...%s\n", bdatae (b, "<Out of memory>"));
+ /* if (out && b) */ fputs (bdatae (out, "<Out of memory>"), stdout);
+ bdestroy (b);
+ bdestroy (out);
+
+Besides being shorter, we can see that error handling can be deferred right
+to the very end. Also, unlike the above two versions, if getenv() returns
+with NULL, the Bstrlib version will not exhibit undefined behavior.
+Initialization starts with the relevant content rather than an extra
+autoinitialization step.
+
+libclc
+------
+
+An attempt to add to the standard C library with a number of common useful
+functions, including additional string functions.
+http://libclc.sourceforge.net/
+
+1. Uses standard char * buffer, and adopts C 99's usage of "restrict" to pass
+ the responsibility to guard against aliasing to the programmer.
+2. Adds no safety or memory management whatsoever.
+3. Most of the supplied string functions are completely trivial.
+
+The goals of libclc and Bstrlib are clearly quite different.
+
+fireString
+----------
+
+http://firestuff.org/
+
+1. Uses standard char * buffer, and adopts C 99's usage of "restrict" to pass
+ the responsibility to guard against aliasing to the programmer.
+2. Mixes char * and length wrapped buffers (estr) functions, doubling the API
+ size, with safety limited to only half of the functions.
+
+Firestring was originally just a wrapper of char * functionality with extra
+length parameters. However, it has been augmented with the inclusion of the
+estr type which has similar functionality to stralloc. But firestring does
+not nearly cover the functional scope of Bstrlib.
+
+Safe C String Library
+---------------------
+
+A library written for the purpose of increasing safety and power to C's string
+handling capabilities.
+http://www.zork.org/safestr/safestr.html
+
+1. While the safestr_* functions are safe in of themselves, interoperating
+ with char * string has dangerous unsafe modes of operation.
+2. The architecture of safestr's causes the base pointer to change. Thus,
+ its not practical/safe to store a safestr in multiple locations if any
+ single instance can be manipulated.
+3. Dependent on an additional error handling library.
+4. Uses reference counting, meaning that it is either not thread safe or
+ slow and not portable.
+
+I think the idea of reallocating (and hence potentially changing) the base
+pointer is a serious design flaw that is fatal to this architecture. True
+safety is obtained by having automatic handling of all common scenarios
+without creating implicit constraints on the user.
+
+Because of its automatic temporary clean up system, it cannot use "const"
+semantics on input arguments. Interesting anomolies such as:
+
+ safestr_t s, t;
+ s = safestr_replace (t = SAFESTR_TEMP ("This is a test"),
+ SAFESTR_TEMP (" "), SAFESTR_TEMP ("."));
+ /* t is now undefined. */
+
+are possible. If one defines a function which takes a safestr_t as a
+parameter, then the function would not know whether or not the safestr_t is
+defined after it passes it to a safestr library function. The author
+recommended method for working around this problem is to examine the
+attributes of the safestr_t within the function which is to modify any of
+its parameters and play games with its reference count. I think, therefore,
+that the whole SAFESTR_TEMP idea is also fatally broken.
+
+The library implements immutability, optional non-resizability, and a "trust"
+flag. This trust flag is interesting, and suggests that applying any
+arbitrary sequence of safestr_* function calls on any set of trusted strings
+will result in a trusted string. It seems to me, however, that if one wanted
+to implement a trusted string semantic, one might do so by actually creating
+a different *type* and only implement the subset of string functions that are
+deemed safe (i.e., user input would be excluded, for example.) This, in
+essence, would allow the compiler to enforce trust propogation at compile
+time rather than run time. Non-resizability is also interesting, however,
+it seems marginal (i.e., to want a string that cannot be resized, yet can be
+modified and yet where a fixed sized buffer is undesirable.)

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+

+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of

+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the

+Better String library Porting Guide
+-----------------------------------
+
+by Paul Hsieh
+
+The bstring library is an attempt to provide improved string processing
+functionality to the C and C++ language. At the heart of the bstring library
+is the management of "bstring"s which are a significant improvement over '\0'
+terminated char buffers. See the accompanying documenation file bstrlib.txt
+for more information.
+
+===============================================================================
+
+Identifying the Compiler
+------------------------
+
+Bstrlib has been tested on the following compilers:
+
+ Microsoft Visual C++
+ Watcom C/C++ (32 bit flat)
+ Intel's C/C++ compiler (on Windows)
+ The GNU C/C++ compiler (on Windows/Linux on x86 and PPC64)
+ Borland C++
+ Turbo C
+
+There are slight differences in these compilers which requires slight
+differences in the implementation of Bstrlib. These are accomodated in the
+same sources using #ifdef/#if defined() on compiler specific macros. To
+port Bstrlib to a new compiler not listed above, it is recommended that the
+same strategy be followed. If you are unaware of the compiler specific
+identifying preprocessor macro for your compiler you might find it here:
+
+http://predef.sourceforge.net/precomp.html
+
+Note that Intel C/C++ on Windows sets the Microsoft identifier: _MSC_VER.
+
+16-bit vs. 32-bit vs. 64-bit Systems
+------------------------------------
+
+Bstrlib has been architected to deal with strings of length between 0 and
+INT_MAX (inclusive). Since the values of int are never higher than size_t
+there will be no issue here. Note that on most 64-bit systems int is 32-bit.
+
+Dependency on The C-Library
+---------------------------
+
+Bstrlib uses the functions memcpy, memmove, malloc, realloc, free and
+vsnprintf. Many free standing C compiler implementations that have a mode in
+which the C library is not available will typically not include these
+functions which will make porting Bstrlib to it onerous. Bstrlib is not
+designed for such bare bones compiler environments. This usually includes
+compilers that target ROM environments.
+
+Porting Issues
+--------------
+
+Bstrlib has been written completely in ANSI/ISO C and ISO C++, however, there
+are still a few porting issues. These are described below.
+
+1. The vsnprintf () function.
+
+Unfortunately, the earlier ANSI/ISO C standards did not include this function.
+If the compiler of interest does not support this function then the
+BSTRLIB_NOVSNP should be defined via something like:
+
+ #if !defined (BSTRLIB_VSNP_OK) && !defined (BSTRLIB_NOVSNP)
+ # if defined (__TURBOC__) || defined (__COMPILERVENDORSPECIFICMACRO__)
+ # define BSTRLIB_NOVSNP
+ # endif
+ #endif
+
+which appears at the top of bstrlib.h. Note that the bformat(a) functions
+will not be declared or implemented if the BSTRLIB_NOVSNP macro is set. If
+the compiler has renamed vsnprintf() to some other named function, then
+search for the definition of the exvsnprintf macro in bstrlib.c file and be
+sure its defined appropriately:
+
+ #if defined (__COMPILERVENDORSPECIFICMACRO__)
+ # define exvsnprintf(r,b,n,f,a) {r=__compiler_specific_vsnprintf(b,n,f,a);}
+ #else
+ # define exvsnprintf(r,b,n,f,a) {r=vsnprintf(b,n,f,a);}
+ #endif
+
+Take notice of the return value being captured in the variable r. It is
+assumed that r exceeds n if and only if the underlying vsnprintf function has
+determined what the true maximal output length would be for output if the
+buffer were large enough to hold it. Non-modern implementations must output a
+lesser number (the macro can and should be modified to ensure this).
+
+2. Weak C++ compiler.
+
+C++ is a much more complicated language to implement than C. This has lead
+to varying quality of compiler implementations. The weaknesses isolated in
+the initial ports are inclusion of the Standard Template Library,
+std::iostream and exception handling. By default it is assumed that the C++
+compiler supports all of these things correctly. If your compiler does not
+support one or more of these define the corresponding macro:
+
+ BSTRLIB_CANNOT_USE_STL
+ BSTRLIB_CANNOT_USE_IOSTREAM
+ BSTRLIB_DOESNT_THROW_EXCEPTIONS
+
+The compiler specific detected macro should be defined at the top of
+bstrwrap.h in the Configuration defines section. Note that these disabling
+macros can be overrided with the associated enabling macro if a subsequent
+version of the compiler gains support. (For example, its possible to rig
+up STLport to provide STL support for WATCOM C/C++, so -DBSTRLIB_CAN_USE_STL
+can be passed in as a compiler option.)
+
+3. The bsafe module, and reserved words.
+
+The bsafe module is in gross violation of the ANSI/ISO C standard in the
+sense that it redefines what could be implemented as reserved words on a
+given compiler. The typical problem is that a compiler may inline some of the
+functions and thus not be properly overridden by the definitions in the bsafe
+module. It is also possible that a compiler may prohibit the redefinitions in
+the bsafe module. Compiler specific action will be required to deal with
+these situations.
+
+Platform Specific Files
+-----------------------
+
+The makefiles for the examples are basically setup of for particular
+environments for each platform. In general these makefiles are not portable
+and should be constructed as necessary from scratch for each platform.
+
+Testing a port
+--------------
+
+To test that a port compiles correctly do the following:
+
+1. Build a sample project that includes the bstrlib, bstraux, bstrwrap, and
+ bsafe modules.
+2. Compile bstest against the bstrlib module.
+3. Run bstest and ensure that 0 errors are reported.
+4. Compile test against the bstrlib and bstrwrap modules.
+5. Run test and ensure that 0 errors are reported.
+6. Compile each of the examples (except for the "re" example, which may be
+ complicated and is not a real test of bstrlib and except for the mfcbench
+ example which is Windows specific.)
+7. Run each of the examples.
+
+The builds must have 0 errors, and should have the absolute minimum number of
+warnings (in most cases can be reduced to 0.) The result of execution should
+be essentially identical on each platform.
+
+Performance
+-----------
+
+Different CPU and compilers have different capabilities in terms of
+performance. It is possible for Bstrlib to assume performance
+characteristics that a platform doesn't have (since it was primarily
+developed on just one platform). The goal of Bstrlib is to provide very good
+performance on all platforms regardless of this but without resorting to
+extreme measures (such as using assembly language, or non-portable intrinsics
+or library extensions.)
+
+There are two performance benchmarks that can be found in the example/
+directory. They are: cbench.c and cppbench.cpp. These are variations and
+expansions of a benchmark for another string library. They don't cover all
+string functionality, but do include the most basic functions which will be
+common in most string manipulation kernels.
+
+...............................................................................
+
+Feedback
+--------
+
+In all cases, you may email issues found to the primary author of Bstrlib at
+the email address: [email protected]

+Better String library Security Statement
+----------------------------------------
+
+by Paul Hsieh
+
+===============================================================================
+
+Introduction
+------------
+
+The Better String library (hereafter referred to as Bstrlib) is an attempt to
+provide improved string processing functionality to the C and C++ languages.
+At the heart of the Bstrlib is the management of "bstring"s which are a

+WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR
+OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF
+ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
+
+Like any software, there is always a possibility of failure due to a flawed
+implementation. Nevertheless a good faith effort has been made to minimize
+such flaws in Bstrlib. Also, use of Bstrlib by itself will not make an
+application secure or free from implementation failures. However, it is the
+author's conviction that use of Bstrlib can greatly facilitate the creation
+of software meeting the highest possible standards of security.
+
+Part of the reason why this document has been created, is for the purpose of
+security auditing, or the creation of further "Statements on Security" for
+software that is created that uses Bstrlib. An auditor may check the claims
+below against Bstrlib, and use this as a basis for analysis of software which
+uses Bstrlib.
+
+===============================================================================
+
+Statement on Security
+---------------------
+
+This is a document intended to give consumers of the Better String Library
+who are interested in security an idea of where the Better String Library
+stands on various security issues. Any deviation observed in the actual
+library itself from the descriptions below should be considered an
+implementation error, not a design flaw.
+
+This statement is not an analytical proof of correctness or an outline of one
+but rather an assertion similar to a scientific claim or hypothesis. By use,
+testing and open independent examination (otherwise known as scientific
+falsifiability), the credibility of the claims made below can rise to the
+level of an established theory.
+
+Common security issues:
+.......................
+
+1. Buffer Overflows
+
+The Bstrlib API allows the programmer a way to deal with strings without
+having to deal with the buffers containing them. Ordinary usage of the
+Bstrlib API itself makes buffer overflows impossible.
+
+Furthermore, the Bstrlib API has a superset of basic string functionality as
+compared to the C library's char * functions, C++'s std::string class and
+Microsoft's MFC based CString class. It also has abstracted mechanisms for
+dealing with IO. This is important as it gives developers a way of migrating
+all their code from a functionality point of view.
+
+2. Memory size overflow/wrap around attack
+
+Bstrlib is, by design, impervious to memory size overflow attacks. The
+reason is it is resiliant to length overflows is that bstring lengths are
+bounded above by INT_MAX, instead of ~(size_t)0. So length addition
+overflows cause a wrap around of the integer value making them negative
+causing balloc() to fail before an erroneous operation can occurr. Attempted
+conversions of char * strings which may have lengths greater than INT_MAX are
+detected and the conversion is aborted.
+
+It is unknown if this property holds on machines that don't represent
+integers as 2s complement. It is recommended that Bstrlib be carefully
+auditted by anyone using a system which is not 2s complement based.
+
+3. Constant string protection
+
+Bstrlib implements runtime enforced constant and read-only string semantics.
+I.e., bstrings which are declared as constant via the bsStatic() macro cannot
+be modified or deallocated directly through the Bstrlib API, and this cannot
+be subverted by casting or other type coercion. This is independent of the
+use of the const_bstring data type.
+
+The Bstrlib C API uses the type const_bstring to specify bstring parameters
+whose contents do not change. Although the C language cannot enforce this,
+this is nevertheless guaranteed by the implementation of the Bstrlib library
+of C functions. The C++ API enforces the const attribute on CBString types
+correctly.
+
+4. Aliased bstring support
+
+Bstrlib detects and supports aliased parameter management throughout the API.
+The kind of aliasing that is allowed is the one where pointers of the same
+basic type may be pointing to overlapping objects (this is the assumption the
+ANSI C99 specification makes.) Each function behaves as if all read-only
+parameters were copied to temporaries which are used in their stead before
+the function is enacted (it rarely actually does this). No function in the
+Bstrlib uses the "restrict" parameter attribute from the ANSI C99
+specification.
+
+5. Information leaking
+
+In bstraux.h, using the semantically equivalent macros bSecureDestroy() and
+bSecureWriteProtect() in place of bdestroy() and bwriteprotect() respectively
+will ensure that stale data does not linger in the heap's free space after
+strings have been released back to memory. Created bstrings or CBStrings
+are not linked to anything external to themselves, and thus cannot expose
+deterministic data leaking. If a bstring is resized, the preimage may exist
+as a copy that is released to the heap. Thus for sensitive data, the bstring
+should be sufficiently presized before manipulated so that it is not resized.
+bSecureInput() has been supplied in bstraux.c, which can be used to obtain
+input securely without any risk of leaving any part of the input image in the
+heap except for the allocated bstring that is returned.
+
+6. Memory leaking
+
+Bstrlib can be built using memdbg.h enabled via the BSTRLIB_MEMORY_DEBUG
+macro. User generated definitions for malloc, realloc and free can then be
+supplied which can implement special strategies for memory corruption
+detection or memory leaking. Otherwise, bstrlib does not do anything out of
+the ordinary to attempt to deal with the standard problem of memory leaking
+(i.e., losing references to allocated memory) when programming in the C and
+C++ languages. However, it does not compound the problem any more than exists
+either, as it doesn't have any intrinsic inescapable leaks in it. Bstrlib
+does not preclude the use of automatic garbage collection mechanisms such as
+the Boehm garbage collector.
+
+7. Encryption
+
+Bstrlib does not present any built-in encryption mechanism. However, it
+supports full binary contents in its data buffers, so any standard block
+based encryption mechanism can make direct use of bstrings/CBStrings for
+buffer management.
+
+8. Double freeing
+
+Freeing a pointer that is already free is an extremely rare, but nevertheless
+a potentially ruthlessly corrupting operation (its possible to cause Win 98 to
+reboot, by calling free mulitiple times on already freed data using the WATCOM
+CRT.) Bstrlib invalidates the bstring header data before freeing, so that in
+many cases a double free will be detected and an error will be reported
+(though this behaviour is not guaranteed and should not be relied on).
+
+Using bstrFree pervasively (instead of bdestroy) can lead to somewhat
+improved invalid free avoidance (it is completely safe whenever bstring
+instances are only stored in unique variables). For example:
+
+ struct tagbstring hw = bsStatic ("Hello, world");
+ bstring cpHw = bstrcpy (&hw);
+
+ #ifdef NOT_QUITE_AS_SAFE
+ bdestroy (cpHw); /* Never fail */
+ bdestroy (cpHw); /* Error sometimes detected at runtime */
+ bdestroy (&hw); /* Error detected at run time */
+ #else
+ bstrFree (cpHw); /* Never fail */
+ bstrFree (cpHw); /* Will do nothing */
+ bstrFree (&hw); /* Will lead to a compile time error */
+ #endif
+
+9. Resource based denial of service
+
+bSecureInput() has been supplied in bstraux.c. It has an optional upper limit
+for input length. But unlike fgets(), it is also easily determined if the
+buffer has been truncated early. In this way, a program can set an upper limit
+on input sizes while still allowing for implementing context specific
+truncation semantics (i.e., does the program consume but dump the extra
+input, or does it consume it in later inputs?)
+
+10. Mixing char *'s and bstrings
+
+The bstring and char * representations are not identical. So there is a risk
+when converting back and forth that data may lost. Essentially bstrings can
+contain '\0' as a valid non-terminating character, while char * strings
+cannot and in fact must use the character as a terminator. The risk of data
+loss is very low, since:
+
+ A) the simple method of only using bstrings in a char * semantically
+ compatible way is both easy to achieve and pervasively supported.
+ B) obtaining '\0' content in a string is either deliberate or indicative
+ of another, likely more serious problem in the code.
+ C) the library comes with various functions which deal with this issue
+ (namely: bfromcstr(), bstr2cstr (), and bSetCstrChar ())
+
+Marginal security issues:
+.........................
+
+11. 8-bit versus 9-bit portability
+
+Bstrlib uses CHAR_BIT and other limits.h constants to the maximum extent
+possible to avoid portability problems. However, Bstrlib has not been tested
+on any system that does not represent char as 8-bits. So whether or not it
+works on 9-bit systems is an open question. It is recommended that Bstrlib be
+carefully auditted by anyone using a system in which CHAR_BIT is not 8.
+
+12. EBCDIC/ASCII/UTF-8 data representation attacks.
+
+Bstrlib uses ctype.h functions to ensure that it remains portable to non-
+ASCII systems. It also checks range to make sure it is well defined even for
+data that ANSI does not define for the ctype functions.
+
+Obscure issues:
+...............
+
+13. Data attributes
+
+There is no support for a Perl-like "taint" attribute, however, an example of
+how to do this using C++'s type system is given as an example.
