       NAME
             ticots - connection-oriented loopback transport provider

       SYNOPSIS
             #include <sys/socket.h>
             s = socket(AF_UNIX, SOCK_STREAM, 0);
             #include <xti.h>
             t = t_open("/dev/ticots", O_RDWR, infop);

       DESCRIPTION
             /dev/ticots is a connection-mode transport provider offering
             service of type T_COTS.

             In the synopsis, s and t are file descriptors for the
             respective endpoints on calls to functions opening a file
             descriptor for a transport endpoint.

             /dev/ticots is typically invoked as the implied device in a
             call to socket or as the first argument in a call to t_open
             and is used to identify the transport protocol that will
             supply a connection-based transport service.

             The device known as /dev/ticots is a ``loopback transport
             provider,'' that is, a stand-alone network at the transport
             level.  Loopback devices are transport providers in every
             sense except one: only one host (the local machine) is
             ``connected to'' a loopback network.

             /dev/ticots may be used as a clone device to find a minor
             available device for the transport user.  It presents a TPI
             (STREAMS-level) interface to application processes and is
             intended to be accessed via the TLI or socket (application-
             level) interface.  It supports address spaces consisting of
             ``flex-addresses,'' that is, arbitrary sequences of octets, of
             length > 0, represented by a netbuf structure, described in
             intro(3).

          Return Values
             The value returned by a call to open an endpoint with
             /dev/ticots is a file descriptor characterizing the endpoint.

      USAGE
            Loopback transports support a local IPC mechanism through the
            TLI and sockets interfaces.  Applications implemented in a
            transport provider-independent manner on a client-server model
            using this IPC are transparently transportable to networked
            environments.

            /dev/ticots supports the same service type (T_COTS) supported
            by the OSI transport-level model and its use is encouraged.
