shutdown(3N)                     UNIX System V                     shutdown(3N)


NAME
      shutdown - shut down part of a full-duplex connection

SYNOPSIS
      int shutdown(int s, int how);

DESCRIPTION
      The shutdown call shuts down all or part of a full-duplex connection on
      the socket associated with s.  If how is 0, then further receives will be
      disallowed.  If how is 1, then further sends will be disallowed.  If how
      is 2, then further sends and receives will be disallowed.

RETURN VALUE
      A 0 is returned if the call succeeds, -1 if it fails.

ERRORS
      The call succeeds unless:

      EBADF               s is not a valid descriptor.

      ENOTSOCK            s is a file, not a socket.

      ENOTCONN            The specified socket is not connected.

      ENOMEM              There was insufficient user memory available for the
                          operation to complete.

      ENOSR               There were insufficient STREAMS resources available
                          for the operation to complete.
