Yes, I do close the socket on the client side right in the same way:

    i = shutdown(SockFd, SHUT_RDWR);
    if(i != 0) {
      // Some error handling
    }
    i = close(SockFd);
    if(i != 0) {
      // Some error handling
    }

No error occurs here. All socket IO should be finished at this point.
btw: Would it be a problem, if there is unread data on one of the sides?
