NAME
SDL_HAS_BUILTIN - Check if the compiler supports a given builtin functionality.
HEADER FILE
Defined in SDL3/SDL_begin_code.h
SYNOPSIS
#include "SDL3/SDL.h" #define SDL_HAS_BUILTIN(x) __has_builtin(x)
DESCRIPTION
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).
AVAILABILITY
