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