A generic function pointer.
Defined in <SDL3/SDL_stdinc.h>
typedef void (*SDL_FunctionPointer)(void);In theory, generic function pointers should use this, instead of
void *, since some platforms could treat code addresses
differently than data addresses. Although in current times no popular
platforms make this distinction, it is more correct and portable to use
the correct type for a generic pointer.
If for some reason you need to force this typedef to be an actual
void *, perhaps to work around a compiler or existing code,
you can define SDL_FUNCTION_POINTER_IS_VOID_POINTER
before including any SDL headers.
This datatype is available since SDL 3.2.0.
