Functions:-General string output routine for any module to use. void gpsd_report(int errlevel UNUSED, const char *fmt, ... ) Provides the outputting of strings to stderr for anyone who needs it. Used extensively by many functions to report errors or progress. Responds according to the errlevel argument, which is filled by the DEBUG command line argument, so that the verbosity of output is conditional on the user's wishes at runtime.
