Detailed Description

Defines interface between QNX6 resource manager and subbus hardware.

A different hardware architecture can be supported by reimplementing these functions.

The basic sanity of the incoming message has been checked by subbus_io_msg before it gets here, so we can at least assume that the message was big enough to include the specified message type, and that the message type is defined.
