Handling messages
QNX SDP8.0Getting Started with the QNX OSDeveloperUser
Once we've registered one or more pathnames, we should then be prepared to
receive messages from clients.
This is done in the usual
way, with the MsgReceive() function call.
There are fewer than 30 well-defined message types that the resource manager handles.
To simplify the discussion and implementation, however, they're broken into two groups.
- Connect messages
- Always contain a pathname; these are either one-shot messages or they establish a context for further I/O messages.
- I/O messages
- Always based on a connect message; these perform further work.
