c - Bind failed: Address already in use -

-

i attempting bind socket port below: 

if( bind(socket_desc,(struct sockaddr *) &server, sizeof(server)) < 0) {     perror("bind failed. error");     return 1; } puts("bind done");

but gives:

$ ./serve    socket created     bind failed. error: address in use

why error occur?

the error means port trying open being used application try using netstat see ports open , use available port.

also check if binding right ip address (i assuming localhost)
