If you mean error codes at exit, no. GPSD is a daemon, so exit codes
indicating fix or no fix would be meaningless.

If you mean in the data GPSD sends to its clients, yes. In the struct
gpsdata ("struct gps_data_t gpsdata;"), there are several flags you
need to look at to determine the state: Do you have a GPS receiver
present? Does it have a fix, and if so of what quality? See gps.h for
the gory details.

GPSD won't retry. It will sit there waiting from input from the GPS
receiver, if any. Watch the appropriate flags as needed. It is up to
the client program to take appropriate actions.

There's lots of documentation on the web site.
