Additions to XTI Interface

The XNS 5 (Unix98) standard introduces some new XTI interfaces. These are briefly described below. The details may be found in the relevant manual pages. These interfaces are not available for TLI users.

Scatter/Gather Data Transfer Interfaces

t_sndvudata(3N): Send a data unit from one or more non-contiguous buffers
t_rcvvudata(3N): Receive a data unit into one or more non-contiguous buffers
t_sndv(3N): Send data or expedited data from one or more non-contiguous buffers on a connection
t_rcvv(3N): Receive data or expedited data sent over a connection and put the data into one or more non-contiguous buffers

XTI Utility Functions

t_sysconf(3N): Get configurable XTI variables

Additional Connection Release Interfaces

t_sndreldata(3N): Initiate/respond to an orderly release with user data
t_rcvreldata(3N): Receive an orderly release indication or confirmation containing user data

Note -

The additional interfacest_sndreldata(3N) and t_rcvreldata(3N) are only for use with a specific transport called "minimal OSI" which is not available on the Solaris platform. These interfaces are not available for use in conjunction with Internet Transports (TCP or UDP).
