/* swigptr.cfg
 * $Header$
 *
 * This file contains two functions :
 *
 *       void  _swig_make_hex(char *_c, void *_ptr, char *type)
 *       char *_swig_get_hex(char *_c, void **ptr, char *type)
 *
 * These are used to convert pointers to and from pointer strings
 * and to perform type checking.
 *
 * You can remap these functions by making a file called "swigptr.cfg" in
 * your the same directory as the interface file you are wrapping.
 *
 * IMPORTANT !!! the function _swig_get_hex returns a non-null char pointer
 * in the event of a type error (this is used to generate an error message).
 * If a type is successfully parsed, a NULL pointer is returned.
 *
 * $Log$
 * Revision 1.1  2002/04/29 19:56:50  RD
 * Since I have made several changes to SWIG over the years to accomodate
 * 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.
 *
 * Revision 1.1.1.1  1999/02/28 02:00:53  beazley
 * Swig1.1
 *
 * Revision 1.5  1996/08/01 16:28:56  dmb
 * Took out unused "dt" variable.
 *
 * Revision 1.4  1996/07/23 14:38:42  dmb
 * Minor change to handling of NULL pointers.
 *
 * Revision 1.3  1996/07/17 15:26:08  dmb
 * Made a minor bug fix so pointers of form _0_Type could be used
 * (as described in the manual).   Disable by compiling with -DNO_ZERO.
 *
 * Revision 1.2  1996/06/10 23:42:10  beazley
 * Added const qualifier.
