Sockets-to-XTI conversion

``Table of XTI/Sockets equivalents'' shows some approximate XTI/sockets equivalents. The comment field describes the differences. Where there is no comment, either the functions are the same or there is no equivalent function in one or the other interface.

Table of XTI/Sockets equivalents

XTI function	Socket function	Comments
t_open	socket
-	socketpair
t_bind	bind	t_bind sets the queue depth for passive sockets, but bind does not. For sockets, the queue length is specified in the call to listen
t_optmgmt	getsockopt setsockopt	t_optmgmt manages only transport options getsockopt and setsockopt can manage options at the transport layer, but also at the socket layer and at arbitrary protocol layers
t_unbind	-
t_close	close
t_getinfo	getsockopt	t_getinfo returns information about the transport. getsockopt can return information about the transport and the socket
t_getprotaddr	getpeername getsockname	t_getprotaddr gets both the local and the remote protocol addresses associated with the transport endpoint. getpeername gets the remote protocol address associated with a socket. getsockname gets the local protocol address associated with a socket
t_getstate	-
t_sync	-
t_alloc	-
t_free	-
t_look	-	getsockopt with the SO_ERROR option returns the same kind of error information as t_look
t_error	perror
t_connect	connect	A connect can be done without first binding the local endpoint. The endpoint must be bound before calling t_connect. A connect can be done on a connectionless endpoint to set the default destination address for datagrams
t_rcvconnect	-
t_listen	listen	t_listen waits for connection indications. listen merely sets the queue depth
t_accept	accept
t_snd	send sendto sendmsg	sendto and sendmsg operate in connection mode as well as datagram mode
t_rcv	recv recvfrom recvmsg	recvfrom and recvmsg operate in connection mode as well as datagram mode.
t_snddis	-
t_rcvdis	-
t_sndrel	shutdown
t_rcvrel	-
t_sndudata	sendto sendmsg
t_rcvudata	recvfrom recvmsg
t_rcvuderr	-
read write	read write	In XTI, you must push the tirdwr module before calling read or write; in sockets, it is sufficient just to call read or write
