Reallocate memory obtained from SDL_SIMDAlloc
void * SDL_SIMDRealloc(void *mem, const size_t len);
|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.|
|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.|
Returns a pointer to the newly-reallocated block, NULL if out of memory.
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.
This function is available since SDL 2.0.14.
