Getting "Address already in use" error using Unix socket

Writing the C source below using Unix local sockets I got an error about the address already in use. After having checked man 7 Unix for further informations I tried to create a sub-folder where executing my program (obviously modifying the sun_path field on the current folder) but the error was ever the same.

Is there someone able to help me?

The source code can be found here: Pastebin

You should unlink() the path file before bind call. You will get this error when file exists during the bind. Either you should ensure to unlink/remove the file before exiting the application or you could always unlink it before bind.

Check man page of bind. Also, note the example given in the man page at the end.
