Remarks

CGlobalHeap implements memory allocation functions using the Win32 global heap functions.

Note

The global heap functions are slower than other memory management functions and do not provide as many features. Therefore, new applications should use the heap functions. These are available in the CWin32Heap class. Global functions are still used by DDE and the clipboard functions.
