Detailed Description

This event is sent to a task when a response comes in. No part of this structure should ever be modified by the caller, other than parts of the buffer. The holy parts of the buffer are the base and size of the buffer. All other parts of the buffer may be used. On event delivery the used region contains the packet.

"id" is the received message id,

"addr" is the host that sent it to us,

"buffer" holds state on the received data.

The "free" routine for this event will clean up itself as well as any buffer space allocated from common pools.
