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.
