Internet Packet Exchange (IPX)

IPX is a datagram (connectionless) service

protocol that allows individual packets to be sent to and received from user processes. It does not support the concept of a connection or reliable delivery. However, guaranteed services (like SPX) can be built on top of IPX. IPX is used in situations where a guaranteed service is not required or where an occasional lost packet is not critical.

The TLI (Transport Layer Interface) library provides routines with which to access IPX. ``Using the IPX protocol'' describes how to use these routines to access IPX. See also ``Transport Layer Interface and X/Open Transport Interface (NET)''.

t_alloc

allocate a

library structure

t_bind

bind an address

to a transport endpoint

t_close

close a

transport endpoint

t_error

produce an

error message

t_free

free a

library structure

t_getinfo

get protocol-specific

service information

t_getstate

get the

current state

t_look

look at the current event

on a transport endpoint

t_open

establish a

transport endpoint

t_optmgmt

manage options for

a transport endpoint

t_rcvudata

receive a

data unit

t_rcvuderr

receive a unit data

error indication

t_sndudata

send a

data unit

t_sync

synchronize the

transport library

t_unbind

disable a

transport endpoint

The structures used by the TLI

interface to IPX are:

• t_bind

• t_info

• t_optmgmt

• t_unitdata

• t_uderr
