Destroys the specified heap object.

HeapDestroy de-commits and releases all the pages of a private heap object, and it invalidates the handle to the heap.

Syntax

BOOL HeapDestroy(
  [in] HANDLE hHeap
);

Parameters

[in] hHeap

A handle to the heap to be destroyed. This handle is returned by the HeapCreate function. Do not use the handle to the process heap returned by the GetProcessHeap function.

Return value

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.
