The XNS 5 (UNIX03) standard introduces some new XTI interfaces. These are briefly described below. You can find the details in the relevant manual pages. These interfaces are not available for TLI users. The scatter-gather data transfer interfaces are:
Send data or expedited data from one or more non-contiguous buffers on a connection
Receive data or expedited data sent over a connection and put the data into one or more non-contiguous buffers
The XTI utility interface t_sysconf(3NSL) gets configurable XTI variables. The t_sndreldata(3NSL) interface initiates and responds to an orderly release with user data. The t_rcvreldata(3NSL) receives an orderly release indication or confirmation containing user data.
