MemAfterReqCompletedWriteA rule (kmdf)
The MemAfterReqCompletedWriteA rule specifies that within the EvtIoWrite callback function, the framework memory object cannot be accessed after the I/O request is completed.
Within the driver's EvtIoWrite callback function, the framework memory object that was retrieved by calling the WdfRequestRetrieveInputMemory method cannot be accessed after calling WdfRequestComplete, WdfRequestCompleteWithInformation, or WdfRequestCompleteWithPriorityBoost on the I/O request.
This rule considers the following eight access methods:

|At compile time|
Run Static Driver Verifier and specify the MemAfterReqCompletedWriteA rule.Use the following steps to run an analysis of your code:
