HeapDestroy    
The HeapDestroy
function destroys the specified heap object. HeapDestroy decommits and
releases all the pages of a private heap object, and it invalidates the handle
of the heap. 
BOOL HeapDestroy(
|     HANDLE hHeap  | // handle to the
  heap  | 
|    ); |  | 
Parameters
hHeap
Specifies the
heap to be destroyed. This parameter should be a heap handle returned by the HeapCreate function. A heap handle
returned by the GetProcessHeap function should not be used. 
Return Values
If the
function succeeds, the return value is nonzero.
If the
function fails, the return value is zero. To get extended error information,
call GetLastError.
Remarks
Processes can
call HeapDestroy without first calling the HeapFree function to
free memory allocated from the heap.
