FN_VMB_CHANNEL_PACKET_COMPLETE callback function

Description

[Some information relates to pre-released product which may be substantially modified before it's commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here.]

The VmbChannelPacketComplete function cleans up any outstanding memory mappings, releases any buffers in use, and, if the opposite endpoint requested a completion packet, sends a completion packet.

Parameters

PacketCompletionContext

A handle that identifies the incoming packet and is used to refer to the packet once processing is finished.

PacketCompletionBuffer

A buffer of completion data to be sent back to the originating endpoint. Although this usually contains just a status value, the contents are up to the client driver.

BufSize

The size, in bytes, of the completion buffer.

Remarks

This function is called when the client driver is finished processing a packet. This function may be called directly from the packet parsing function or it may be called later.

[!IMPORTANT] This function is called through the VMBus Kernel Mode Client Library (KMCL) interface, provided by the Vmbkmcl.sys bus driver. This is a client function accessed from the KMCL_CLIENT_INTERFACE_V1 structure.

For more information, see the Remarks section of the KMCL_CLIENT_INTERFACE_V1.
