Programming with sockets

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
