Can I have any API to find out the open ports ( port is being used) in any application in my Win XP. Like 1098 can be used by RMI, Outlook or firefox. As the range of valid port is 1024 to 49,151. but these can be used in any other applications. But the range of 49,152 to 65,535 is full free port.
Is there any free third party application to find out these ,so that I can use it in my application.
