IWDFWorkItem::Flush 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 Flush method returns after this interface's work item has been serviced.
Syntax
void Flush();
Return value
None
Remarks
If a driver calls the Flush method, the method does not return until a worker thread has removed the specified work item from the work-item queue and called the driver's OnWorkItem callback function, and the OnWorkItem callback function has subsequently returned after processing the work item.
For more information, see Using Work Items.
