A handle to the heap of the calling process indicates success. NULL indicates failure. To get extended error information, call GetLastError.
The GetProcessHeap function allows you to allocate memory from the process heap without having to first create a heap with the HeapCreate function, as shown in this example.
HeapAlloc(GetProcessHeap(), 0, dwBytes);
|The handle obtained by calling this function should not be used in calls to the HeapDestroy function.|
