Comments

The stream class driver calls the minidriver's StrMiniReceiveStreamDataPacket routine to handle read and write requests for a specific stream.

The minidriver registers its StrMiniReceiveStreamDataPacket routine as follows: When the class driver opens the stream, it passes a SRB_OPEN_STREAM request block to the minidriver's StrMiniReceiveDevicePacket routine. The StreamObject of the request packet points to a HW_STREAM_OBJECT. The minidriver sets the ReceiveDataPacket member of the structure pointed to by pSRB->StreamObject to the minidriver's StrMiniReceiveDataPacket routine.

Upon completion of its handling of the request, the minidriver passes the structure back to the class driver by calling StreamClassStreamNotification(StreamRequestComplete, pSRB->StreamObject, pSRB).

See information on relevant SRB codes in Stream Class SRB Reference.

When the minidriver finishes its processing of the request, it enters the return status of the operation in pSRB->Status. The minidriver should enter STATUS_SUCCESS for normal successful processing. If the minidriver does not support that Command value, it should set pSRB->Status to STATUS_NOT_IMPLEMENTED. If there is a device hardware error that prevents the minidriver from completing the request, it should set pSRB->Status to STATUS_IO_DEVICE_ERROR. Other error codes the routine uses in specific circumstances are listed above with the specific Command code.
