The HeapLock function attempts to acquire the critical section object, or lock, that is associated with a specified heap.
If the function succeeds, the calling thread owns the heap lock. Only the calling thread will be able to allocate or release memory from the heap. The execution of any other thread of the calling process will be blocked if that thread attempts to allocate or release memory from the heap. Such threads will remain blocked until the thread that owns the heap lock calls the HeapUnlock function.
BOOL HeapLock(
HANDLE hHeap |
// handle to the heap to lock for exclusive thread access |
); |
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.
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.
