NAME

ticlts, ticots, ticotsord- loopback transport providers

SYNOPSIS

#include <sys/ticlts.h>

#include <sys/ticots.h>

#include <sys/ticotsord.h>

DESCRIPTION

The devices known as ticlts , ticots , and ticotsord are ``loopback transport providers,'' that is, stand-alone networks at the transport level. Loopback transport providers are transport providers in every sense except one: only one host (the local machine) is ``connected to'' a loopback network. Loopback transports present a TPI (STREAMS-level) interface to application processes and are intended to be accessed via the TLI (application-level) interface. They are implemented as clone devices and support address spaces consisting of ``flex-addresses,'' that is, arbitrary sequences of octets of length > 0, represented by a netbuf structure.

ticlts is a datagram-mode transport provider. It offers (connectionless) service of type T_CLTS . Its default address size is TCL_DEFAULTADDRSZ . ticlts prints the following error messages (see t_rcvuderr(3NSL) ):

TCL_BADADDR

bad address specification

TCL_BADOPT

bad option specification

TCL_NOPEER

bound

TCL_PEERBADSTATE

peer in wrong state

ticots is a virtual circuit-mode transport provider. It offers (connection-oriented) service of type T_COTS . Its default address size is TCO_DEFAULTADDRSZ . ticots prints the following disconnect messages (see t_rcvdis(3NSL) ):

TCO_NOPEER

no listener on destination address

TCO_PEERNOROOMONQ

peer has no room on connect queue

TCO_PEERBADSTATE

peer in wrong state

TCO_PEERINITIATED

peer-initiated disconnect

TCO_PROVIDERINITIATED

provider-initiated disconnect

ticotsord is a virtual circuit-mode transport provider, offering service of type T_COTS_ORD (connection-oriented service with orderly release). Its default address size is TCOO_DEFAULTADDRSZ . ticotsord prints the following disconnect messages (see t_rcvdis(3NSL) ):

TCOO_NOPEER

no listener on destination address

TCOO_PEERNOROOMONQ

peer has no room on connect queue

TCOO_PEERBADSTATE

peer in wrong state

TCOO_PEERINITIATED

provider-initiated disconnect

TCOO_PROVIDERINITIATED

peer-initiated disconnect

USAGE

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

Transport provider-independent applications must not include the headers listed in the synopsis section above. In particular, the options are (like all transport provider options) provider dependent.

ticlts and ticots support the same service types (T_CLTS and T_COTS ) supported by the OSI transport-level model.

ticotsord supports the same service type (T_COTSORD ) supported by the TCP/IP model.
