NAME¶

SDL_FunctionPointer - A generic function pointer.

HEADER FILE¶

Defined in SDL3/SDL_stdinc.h

SYNOPSIS¶

#include "SDL3/SDL.h"

typedef void (*SDL_FunctionPointer)(void);

DESCRIPTION¶

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.

AVAILABILITY¶

This datatype is available since SDL 3.1.3.
