t_open (ULTRIX) t_open (ULTRIX)
NAME
t_open - Establishes a transport end-point
DIFFERENCES
The Transmission Control Protocol (TCP) and User Datagram Protocol
(UDP) transport providers are supported by both ULTRIX and Digital UNIX
X/Open Transport Interface (XTI). However, when creating a transport
end point with the t_open call, ULTRIX does not need device information
to specify a transport provider. In the Digital UNIX system, this
information must be present because XTI is implemented using the xtiso
pseudo-streams driver.
You must change all your t_open calls to reflect this change for both
TCP and UDP transport providers or change your application to determine
the end point at run time. For example:
#ifdef __osf__
t_open ("~/dev/streams/xtiso/tcp", ...)
#else
t_open ("tcp", ...)
#endif
