al_free - Man Page

#define al_free(p) \
   (al_free_with_context((p), __LINE__, __FILE__, __func__))

Like free() in the C standard library, but the implementation may be overridden.

Additionally, on Windows, a memory block allocated by one DLL must be freed from the same DLL. In the few places where an Allegro function returns a pointer that must be freed, you must use al_free(3) for portability to Windows.

This is a macro.
