(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_memmove

Copy memory ranges that might overlap.

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

void * SDL_memmove(void *dst, const void *src, size_t len);

Function Parameters

void *	dst	The destination memory region. Must not be NULL.
const void *	src	The source memory region. Must not be NULL.
size_t	len	The length in bytes of both dst and src.

Return Value

Remarks

It is okay for the memory regions to overlap. If you are confident that the regions never overlap, using SDL_memcpy() may improve performance.
