        !            30: .SH DESCRIPTION
        !            31: CLTP is a simple, unreliable datagram protocol which is accessed
        !            32: via the SOCK_DGRAM abstraction for the ISO
        !            33: protocol family.  CLTP sockets are connectionless, and are
        !            34: normally used with the
        !            35: .I sendto 
        !            36: and
        !            37: .IR recvfrom 
        !            38: calls, though the
        !            39: .IR connect (2)
        !            40: call may also be used to fix the destination for future
        !            41: packets (in which case the 
        !            42: .IR recv (2)
        !            43: or
        !            44: .IR read (2)
        !            45: and 
        !            46: .IR send (2)
        !            47: or
        !            48: .IR write(2)
        !            49: system calls may be used).
        !            50: .PP
        !            51: CLTP address formats are identical to those used by TP.
        !            52: In particular CLTP provides a service selector in addition
        !            53: to the normal ISO NSAP.  Note that the CLTP selector
        !            54: space is separate from the TP selector space (i.e. a CLTP selector
        !            55: may not be \*(lqconnected\*(rq to a TP selector).
        !            56: .PP
        !            57: Options at the CLNP network level may be used with CLTP; see
        !            58: .IR clnp (4).
        !            59: .SH DIAGNOSTICS
        !            60: A socket operation may fail with one of the following errors returned:
        !            61: .TP 15
        !            62: [EISCONN]
        !            63: when trying to establish a connection on a socket which
        !            64: already has one, or when trying to send a datagram with the destination
        !            65: address specified and the socket is already connected;
        !            66: .TP 15
        !            67: [ENOTCONN]
        !            68: when trying to send a datagram, but
        !            69: no destination address is specified, and the socket hasn't been
        !            70: connected;
        !            71: .TP 15
        !            72: [ENOBUFS]
        !            73: when the system runs out of memory for
        !            74: an internal data structure;
        !            75: .TP 15
        !            76: [EADDRINUSE]
        !            77: when an attempt
        !            78: is made to create a socket with a selector which has already been
        !            79: allocated;
        !            80: .TP 15
        !            81: [EADDRNOTAVAIL]
        !            82: when an attempt is made to create a 
        !            83: socket with a network address for which no network interface
        !            84: exists.
