SDL_SIMDRealloc

Reallocate memory obtained from SDL_SIMDAlloc

Header File

Syntax

void * SDL_SIMDRealloc(void *mem, const size_t len);

Function Parameters

void *	mem	The pointer obtained from SDL_SIMDAlloc. This function also accepts NULL, at which point this function is the same as calling SDL_SIMDAlloc with a NULL pointer.
const size_t	len	The length, in bytes, of the block to allocated. The actual allocated block might be larger due to padding, etc. Passing 0 will return a non-NULL pointer, assuming the system isn't out of memory.

Return Value

(void *) Returns a pointer to the newly-reallocated block, NULL if out of memory.

Remarks

It is not valid to use this function on a pointer from anything but SDL_SIMDAlloc(). It can't be used on pointers from malloc, realloc, SDL_malloc, memalign, new[], etc.

Version

This function is available since SDL 2.0.14.
