[gpsd-users] gps_read () message buffer

[Charles Curley]

Having done a bit of sleuthing in the gpsd source, I think I have some
additional documentation for gps_read. See the attached diff.

Please check it for accuracy!

One request....

* I found the value for the size of the buffer by reading the source for
  cgps, and tracking down where GPS_JSON_RESPONSE_MAX was defined, in
  gps_json.h. That value is likely to grow in the future. Would you
  please provide a suitable #define in gps.h?

Thank you

the word to its mere embellishments, such as arts and sciences; but
the true distinction between it and barbarism is, that the one
presents a state of society under the protection of just and
well-administered law, and the other is left to the chance government
of brute force."
