Can we determine information about open socket connections?

[kolban]

I recently found that I was running a broken app that ran out of sockets (max = 16). It would have helped me a lot if I could have "queried" the environment to obtain a list of TCP/UDP/Socket connections in use. Are there are APIs that I can use to "interrogate" the environment to find out what connections (inbound, outbound or listening) that may be in my environment?
