shutdown(3N)                                                   shutdown(3N)


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

   SYNOPSIS
         shutdown(s, how)
         int s, 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.

   NOTES
         The how values should be defined constants.
