(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_BYTEORDER

A macro that reports the target system's byte order.

Header File

Syntax

#define SDL_BYTEORDER   SDL_LIL_ENDIAN___or_maybe___SDL_BIG_ENDIAN

Remarks

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

Version

This macro is available since SDL 3.1.3.
