special cases and other things in wxPython, and since I plan on making several more, I've decided to put the SWIG sources in wxPython's CVS instead of relying on maintaining patches. This effectivly becomes a fork of an obsolete version of SWIG, :-( but since SWIG 1.3 still doesn't have some things I rely on in 1.1, not to mention that my custom patches would all have to be redone, I felt that this is the easier road to take. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@15307 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

|
|
* This file contains supporting code for the SWIG run-time type checking
|
|
* mechanism. The following functions are available :
|
|
*
|
|
* SWIG_RegisterMapping(char *origtype, char *newtype, void *(*cast)(void *));
|
|
*
|
|
* Registers a new type-mapping with the type-checker. origtype is the
|
|
* original datatype and newtype is an equivalent type. cast is optional
|
|
* pointer to a function to cast pointer values between types (this
|
|
* is typically used to cast pointers from derived classes to base classes in C++)
|
|
*
|
|
* SWIG_MakePtr(char *buffer, void *ptr, char *typestring);
|
|
*
|
|
* Makes a pointer string from a pointer and typestring. The result is returned
|
|
* in buffer which is assumed to hold enough space for the result.
|
|
*
|
|
* char * SWIG_GetPtr(char *buffer, void **ptr, char *type)
|
|
*
|
|
* Gets a pointer value from a string. If there is a type-mismatch, returns
|
|
* a character string to the received type. On success, returns NULL.
|
|
*
|
|
*
|
|
* You can remap these functions by making a file called "swigptr.swg" in
|
|
* your the same directory as the interface file you are wrapping.
|
|
*
|
|
* These functions are normally declared static, but this file can be
|
|
* can be used in a multi-module environment by redefining the symbol
|
|
* SWIGSTATIC.
