SDL_FILE - Man Page

#include <SDL3/SDL_assert.h>

#define SDL_FILE    __FILE_NAME__

This macro is only defined if it isn't already defined, so to override it (perhaps with something that doesn't provide path information at all, so build machine information doesn't leak into public binaries), apps can define this macro before including SDL.h or SDL_assert.h.

This macro is available since SDL 3.2.0.
