If you are simply wrapping the system calls then you are probably not gaining anything on using the standard malloc - thats all they are doing.

It's more common to malloc (or HeapAlloc() etc ) a single block of memory at the start of the program and manage the allocation into this yourself, this can be more efficient if you know you are going to be creating/discarding a lot of small blocks of memory regularly.
