sdlAlignedAlloc function

Pointer<NativeType> sdlAlignedAlloc(
  1. int alignment,
  2. int size
)

Allocate memory aligned to a specific alignment.

The memory returned by this function must be freed with SDL_aligned_free(), not SDL_free().

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

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

\param alignment the alignment of the memory. \param size the size to allocate. \returns a pointer to the aligned memory, or NULL if allocation failed.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.1.3.
