Probing for TCP Connections

[kterry]

I am working on an app for work that checks to make sure a connection is present, and if not, it will restart an application. Is there a way to probe for a certain TCP connection in netstat? Or is there a library that I can use?

I am very new to C...I'm coming from PHP development :)

What OS are you using? (And you are using C, correct, not C++ - just making sure as they are different.)

This will be compiled to run on Windows XP.
C is the language I will be using :)
