|
* Description: s_nsBulkOutIoCompleteWrite
|
|
|
|
* 1a) Indicate to the protocol the status of the write.
|
|
|
|
* 1b) Return ownership of the packet to the protocol.
|
|
|
|
*
|
|
|
|
* 2) If any more packets are queue for sending, send another packet
|
|
|
|
* to USBD.
|
|
|
|
* If the attempt to send the packet to the driver fails,
|
|
|
|
* return ownership of the packet to the protocol and
|
|
|
|
* try another packet (until one succeeds).
|
|
|
|
*
|
|
|
|
* Parameters:
|
|
|
|
* In:
|
|
|
|
* pdoUsbDevObj - pointer to the USB device object which
|
|
|
|
* completed the irp
|
|
|
|
* pIrp - the irp which was completed by the
|
|
|
|
* device object
|
|
|
|
* pContext - the context given to IoSetCompletionRoutine
|
|
|
|
* before calling IoCallDriver on the irp
|
|
|
|
* The pContext is a pointer to the USB device object.
|
|
|
|
* Out:
|
|
|
|
* none
|
|
|
|
*
|
|
|
|
* Return Value: STATUS_MORE_PROCESSING_REQUIRED - allows the completion routine
|
|
|
|
* (IofCompleteRequest) to stop working on the irp.
