Hi Umesh,
That printf() is quite unlikely to produce anything sensible (and unless
there is a 0 byte somewhere in anInstance it might try to print your
computers entire memory..). Us telling the compiler that it
should consider anInstance as an array of char:s does not mean that it
becomes a zero-terminated string that we could give to printf.
To determine whether anInstance got the right format or not you should
test to decode it with the same code as FlightGear uses. Either by copying
it to your application or by tracing fgfs or adding some temporary
printouts to it. (I'd do the latter as that would also tell me whether my
UDP-packets got through at all.)

I have a simple application that sends UDP packets to FlightGear here:
http://www.gidenstam.org/FlightGear/HeadTracking/
However, it does not talk to NetFDM but to a head tracking component that
only exists as a patch somewhere at the moment.
