Regular malloc aligns memory suitable for any object type with a fundamental alignment. The aligned_alloc is useful for over-aligned allocations, such as to SSE, cache line, or VM page boundary. This function is not supported in Microsoft C Runtime library because its implementation of std::...
_aligned_offset_mallocvalidates its parameters. Ifalignmentisn't a power of 2, or ifoffsetis non-zero and greater than or equal tosize, this function invokes the invalid parameter handler, as described inParameter validation. If execution is allowed to continue, this function returnsNULLand sets...
