        !            13: .SH DESCRIPTION
        !            14: The raw imp socket provides direct access to the
        !            15: .IR imp (4)
        !            16: network interface.  Users send packets through
        !            17: the interface using the 
        !            18: .IR send (2)
        !            19: calls, and receive packets with the
        !            20: .IR recv (2),
        !            21: calls.  All outgoing packets must have space for an 1822 96-bit
        !            22: leader on the front.  Likewise, packets received
        !            23: by the user will have this leader on the front.  The
        !            24: 1822 leader and the legal values for the various fields
        !            25: are defined in the include file
        !            26: .RI < netimp/if_imp.h >.
        !            27: .PP
        !            28: The raw imp interface automatically installs the length
        !            29: and destination address in the 1822 leader of all
        !            30: outgoing packets; these need not be filled in by the user.
        !            31: .SH DIAGNOSTICS
        !            32: An operation on a socket may fail with one of the following
        !            33: errors:
        !            34: .TP 15
        !            35: [EISCONN]
        !            36: when trying to establish a connection on a socket which
        !            37: already has one, or when trying to send a datagram with the destination
        !            38: address specified and the socket is already connected;
        !            39: .TP 15
        !            40: [ENOTCONN]
        !            41: when trying to send a datagram, but
        !            42: no destination address is specified, and the socket hasn't been
        !            43: connected;
        !            44: .TP 15
        !            45: [ENOBUFS]
        !            46: when the system runs out of memory for
        !            47: an internal data structure;
        !            48: .TP 15
        !            49: [EADDRNOTAVAIL]
        !            50: when an attempt is made to create a 
        !            51: socket with a network address for which no network interface
        !            52: exists.
