SHUTDOWN(3N-SVR4)   RISC/os Reference Manual    SHUTDOWN(3N-SVR4)



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.
