The HeapUnlock function releases ownership of the critical section object, or lock, that is associated with a specified heap. The HeapUnlock function reverses the action of the HeapLock function.
BOOL HeapUnlock(
HANDLE hHeap |
// handle to the heap to unlock |
); |
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.
The HeapLock function is primarily useful for preventing the allocation and release of heap memory by other threads while the calling thread uses the HeapWalk function. The HeapUnlock function is the inverse of HeapLock.
Each call to HeapLock must be matched by a corresponding call to the HeapUnlock function. Failure to call HeapUnlock will block the execution of any other threads of the calling process that attempt to access the heap.
