SDL_HAS_BUILTIN(3) SDL3 FUNCTIONS SDL_HAS_BUILTIN(3)

SDL_HAS_BUILTIN - Check if the compiler supports a given builtin functionality.

Defined in SDL3/SDL_begin_code.h

#include "SDL3/SDL.h"
#define SDL_HAS_BUILTIN(x) __has_builtin(x)

This allows preprocessor checks for things that otherwise might fail to compile.

Supported by virtually all clang versions and more-recent GCCs. Use this instead of checking the clang version if possible.

On compilers without has_builtin support, this is defined to 0 (always false).

This macro is available since SDL 3.2.0.
