SDL_PLATFORM_LINUX(3) SDL3 FUNCTIONS SDL_PLATFORM_LINUX(3)

SDL_PLATFORM_LINUX - A preprocessor macro that is only defined if compiling for Linux.

Defined in SDL3/SDL_platform_defines.h

#include "SDL3/SDL.h"
#define SDL_PLATFORM_LINUX 1

Note that Android, although ostensibly a Linux-based system, will not define this. It defines SDL_PLATFORM_ANDROID

instead.

This macro is available since SDL 3.2.0.
