_aligned_malloc is based on malloc._aligned_malloc is marked __declspec(noalias) and __declspec(restrict), meaning that the function is guaranteed not to modify global variables and that the pointer returned isn't aliased. For more information, see noalias and restrict....

C11 is supported, so you can just callaligned_alloc (16, size). void *mem = malloc(1024+16); void *ptr = ((char *)mem+16) & ~ 0x0F; memset_16aligned(ptr, 0, 1024); free(mem); On many 64-bit systems, the pointer returned bymalloc()is indeed aligned on a 16-byte boundary...
