SyncReqSend rule (kmdf)
The SyncReqSend rule specifies that all synchronous send requests are done by using synchronous-specific KMDF device driver interface methods, and that the methods have a nonzero timeout value set.
If the driver calls a WDFxxxSendXXXSynchronously method without setting a valid timeout, the thread can become stalled if hardware does not respond promptly.
How to test
|At compile time|
Run Static Driver Verifier and specify the SyncReqSend rule.Use the following steps to run an analysis of your code:
