    Network Programming in C

    I used setsockopt() in the program, but it does not work either? On the server side: I used setsockopt before I bind() listenfd to the serversocket. But after clients requested, then exit and the server responses, then exit. The socket still does not released. Why is that happen?

    Network Programming in C
