/I am using 2.96 version. I couldn't get 3.0 compiled on my machine (x86_64, 
CentOS 5.5, kernel 2.6.18-194.26.1.el5) and had to give up on that eventually 
in favor of something working.

/> I see that there is no test of the return value from gps_open (). That might 
tell you something./
gps_open returns a pointer to struct in this version, not an integer.

/> In your else clause, you should first examine gpsdata->set and only proceed 
if you have valid fix data./
That's right and that's how I am actually doing it. But I modified the code 
while posting it to show how I could still see the values of lat/long/alt.

I also noticed that the output of 'gpspipe -r' doesn't show GPGLL messages which 
probably show the value of gpsdata->fix.status, right?
