How to free a port?

hi all,

Im using a tcp socket for communication. After all the communications I close the socket and bind another socket to the same port. But it shows bind error. I see it is due to the port no being used immediately. But i am closing the first socket before the binding the second one to the same port. Why is the port not set free? How can i do it (set the port free)?

Thank you
