introduce TLI/XTI
Description
The X/Open Transport Interface (XTI) is a library of
functions used to write networked applications over a transport
provider protocol such as TCP/IP.
XTI is derived from the Transport Level Interface (TLI).
Both XTI and TLI are Application Program Interfaces
(APIs) that allow application programs to access transport
providers in a nearly transport-independent fashion. The two interfaces have
their own libraries and header files but there are few differences between
them otherwise. Differences between the APIs are noted to allow
applications to be ported.
XTI uses the header file
<xti.h > and the library xti .
TLI uses the header file
<sys/tiuser.h > and the library nsl (Network Services
Library).
