GetProcessHeap function

Retrieves a handle to the default heap of the calling process. This handle can then be used in subsequent calls to the heap functions.

Syntax

HANDLE GetProcessHeap(

);

Parameters

This function has no parameters.

Return Value

If the function succeeds, the return value is a handle to the calling process's heap.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

Remarks

The GetProcessHeap function obtains a handle to the default heap for the calling process. A process can use this handle to allocate memory from the process heap without having to first create a private heap using the HeapCreate function.

Windows Server 2003 and Windows XP:  To enable the low-fragmentation heap for the default heap of the process, call the HeapSetInformation function with the handle returned by GetProcessHeap.

Examples

For an example, see Getting Process Heaps.
