Temat: Re: [Frei0r] Endian independence (uint_8 vs uint_32 pointers)
Hi Marko,
there was some discussion of this a while ago on the older list. IIRC
we decided for the next version to add macros to the header.

The code is very simple, e.g. if (FREI0R_BYTE_ORDER==FREI0R_LITTLE_ENDIAN) ....


In the header, somethin like:

#ifndef IS_MINGW
#ifndef IS_SOLARIS
#include <endian.h>
#define FREI0R_BYTE_ORDER __BYTE_ORDER
#define FREI0R_LITTLE_ENDIAN __LITTLE_ENDIAN
#define FREI0R_BIG_ENDIAN __BIG_ENDIAN
#else
// solaris

#endif
#else // mingw

#define FREI0R_LITTLE_ENDIAN 1
#define FREI0R_BIG_ENDIAN 0
#define FREI0R_BYTE_ORDER FREI0R_LITTLE_ENDIAN

#endif
