NAME
SDL_BYTEORDER - A macro that reports the target system's byte order.
HEADER FILE
Defined in SDL3/SDL_endian.h
SYNOPSIS
#include "SDL3/SDL.h"
#define SDL_BYTEORDER SDL_LIL_ENDIAN___or_maybe___SDL_BIG_ENDIAN
DESCRIPTION
This is set to either SDL_LIL_ENDIAN
or
SDL_BIG_ENDIAN
(and maybe other values in the future, if something else becomes popular). This can be tested with the
preprocessor, so decisions can be made at compile time.
#if SDL_BYTEORDER == SDL_BIG_ENDIAN
SDL_Log("This system is bigendian.");
#endif
AVAILABILITY
This macro is available since SDL 3.2.0.
