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

SDL_HAS_BUILTIN

Check if the compiler supports a given builtin functionality.

Header File

Defined in <SDL3/SDL_begin_code.h>

Syntax

#define SDL_HAS_BUILTIN(x) __has_builtin(x)

Remarks

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).

Version

This macro is available since SDL 3.1.3.
