Check internet connection

[daveoffy]

I have been trying to check Internet connection but all ways I have tried have failed. Some example code would be great, or the package to use. Thanks very much.

What compiler and OS?

[daveoffy]

Linux, and it is using gcc to compile it.

I got it working. I used if(system(ping -c 1 www.google.com)){ printf("Not Connected"); }

FYI: I couldn't edit the old post, it was past 30 minutes.

The easiest way is to use a socket to connect to a known stable server. If it succeeds you now know you've got an internet connection. If it fails, you can use error messages or assumptions to determine the status.
