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.

NOTES
     The how values should be defined constants.
