Remarks
CWin32Heap implements memory allocation methods using the Win32 heap allocation functions, including HeapAlloc and HeapFree. Unlike other Heap classes, CWin32Heap requires a valid heap handle to be provided before memory is allocated: the other classes default to using the process heap. The handle can be supplied to the constructor or to the CWin32Heap::Attach method. See the CWin32Heap::CWin32Heap method for more details.
Example
