[ale] Open port

[Jeff Tillotson]

In C, is there a way to check if a port is open prior to opening it?   I have 
lookef at getsockopt but that won't so what I want.  I have search the web 
and "UNIX Networking Programming" and there isn't an answer there.  

What I need is to check if a port is already open.  If it is open then I just 
exit the app.  If it isn't then I will bind to the port and all is good.

Any assistance would be appreciated.  

Regards,
J
