Allocate memory aligned to a specific value


SDL_MALLOC void* SDL_aligned_alloc(size_t alignment, size_t size);

Function Parameters

alignment the alignment requested
size the size to allocate

Return Value

Returns a pointer to the aligned memory


If alignment is less than the size of void *, then it will be increased to match that.

The returned memory address will be a multiple of the alignment value, and the amount of memory allocated will be a multiple of the alignment value.

The memory returned by this function must be freed with SDL_aligned_free()


This function is available since SDL 3.0.0.
