A version of this page is also available for
4/8/2010
This function obtains a handle to the heap of the calling process. This handle can then be used in calls to the HeapAlloc, HeapReAlloc, HeapFree, and HeapSize functions.
Syntax
HANDLE GetProcessHeap(VOID);
Parameters
None.
Return Value
A handle to the heap of the calling process indicates success. NULL indicates failure. To get extended error information, call GetLastError.
Remarks
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);
Note
The handle obtained by calling this function should not be used in calls to the HeapDestroy function.
