* srvmgt_report_state(...)
--> report the service state to the supervisor
--> states could be eg.
* SRVMGT_STATE_STARTUP -- still within the startup phase
* SRVMGT_STATE_READY_LOCAL -- ready for local clients only
* SRVMGT_STATE_READY_ALL -- ready for all clients
* SRVMGT_STATE_BUSY -- too busy to process new requests
* SRVMGT_STATE_SHUTDOWN -- shutting down, still finishing
queued requests
* SRVMGT_STATE_DEFERRED -- temporarily can't accept new
requests (eg. overload)
* SRVMGT_STATE_WAITING -- wait for resource (eg. printer
needs paper or ink)
* SRVMGT_STATE_OFFLINE -- completely offline (eg. due some
fatal error)
Reporting state is usefull, but this could be achieved by writing
the state in plain text to stdout. It is up to the supervisr to
establish a pipe between itself and the daemon's stdout. If there isn't
a supervisor, then writing to /dev/null doesn't harm. Or why not write
to a file in /run? Anyway, I don't think it deserves to link to a
library to perform such a simple thing.
