OutputBufferAPI rule (kmdf)
The OutputBufferAPI rule specifies that the correct DDIs for buffer retrieval are used in the EvtIoWrite callback function. Within the EvtIoWrite callback function, the following DDIs cannot be called for buffer retrieval:
WdfRequestRetrieveOutputBuffer WdfRequestRetrieveUnsafeUserOutputBuffer WdfRequestRetrieveOutputWdmMdl WdfRequestRetrieveOutputMemory
Driver model: KMDF
