AW: gpsd and as-needed patches

hi vlatko, thanx for your patches. i don't have knowledge about gpsd api. before i can apply them, i need to know about gps_waiting() function. the osmo_gpsd_cb() function in common/gps.c is called when there is data to be read from gpsd. this function (like any other function) may not delay or block. (except for the CPU processing time of the function.) if no data is available from gpsd, the function must continue with "goto gps_not_ready;" immidately. what will gps_waiting() do in case there is no (complete) information available? regards, andreas
