IWDFIoQueue::StopSynchronously method (wudfddi.h)
[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]
The StopSynchronously method prevents an I/O queue from delivering I/O requests, but the queue receives and stores new requests. The method returns after all delivered requests have been canceled or completed.
Syntax
void StopSynchronously();
Return value
None
Remarks
The StopSynchronously method is the synchronous version of the IWDFIoQueue::Stop method. That is, StopSynchronously does not return to the driver until the queue stops.
The StopSynchronously method enables the queue to receive new requests, even if the queue was not receiving new requests before the driver called StopSynchronously. For example, a driver might call IWDFIoQueue::Drain, which causes the framework to stop adding new I/O requests to the queue. The driver's subsequent call of StopSynchronously causes the framework to resume adding requests to the queue.
