/* ------------------------------------------------------------
* Primitive type fragments and macros
* ------------------------------------------------------------ */
/*
This file provide fragments and macros for the C/C++ primitive types.
The file defines default fragments for the following types:
bool
signed char
unsigned char
signed wchar_t // in C++
unsigned wchar_t // in C++
short
unsigned short
int
unsigned int
float
size_t
ptrdiff_t
which can always be redefined in the swig target languge if needed.
The fragments for the following types, however, need to be defined
in the target language always:
long
unsigned long
long long
unsigned long long
double
If they are not provided, an #error directive will appear in the
wrapped code.
--------------------------------------------------------------------
This file provides the macro
%typemaps_primitive(CheckCode, Type)
which generate the typemaps for a primitive type with a given
checkcode. It is assumed the the primitive type is 'normalized' and
the corresponding SWIG_AsVal(Type) and SWIG_From(Type) methods are
provided via fragments.
The following auxiliar macros (explained with bash pseudo code) are
also defined:
%apply_ctypes(Macro)
for i in C Type
do
Macro($i)
done
%apply_cpptypes(Macro)
for i in C++ Type
do
Macro($i)
done
%apply_ctypes_2(Macro2)
for i in C Type
do
for j in C Type
do
Macro_2($i, $j)
done
done
%apply_cpptypes_2(Macro2)
for i in C++ Type
do
for j in C++ Type
do
Macro_2($i, $j)
done
done
%apply_checkctypes(Macro2)
for i in Check Type
do
Macro2(%checkcode($i), $i)
done
