Allocate memory in Windows

Question

Possible Duplicate:
malloc() vs. HeapAlloc()

I know we can use malloc/free in C to allocate/release heap memory, and use new/delete in C++ to do the similar things.

As for Windows, I occasionally saw people use HeapAlloc etc APIs to allocate memory, which are the differences from the C/C++ counterparts?

And which is the best way to allocate a wchar_t buffer on heap which will be used as input for some Windows APIs?

If you have to ask, don't use `HeapAlloc`. You're not the audience for that function. — Kerrek SB, Oct 14 '12 at 02:46
The best way is most likely a `std::wstring` or `std::vector`. — chris, Oct 14 '12 at 02:46

malloc/new are implemented using HeapAlloc, so there is very little practical difference. There are of course the implementation differences; malloc will return null on failure, new will throw, etc.
