- Hello,
- A while back I posted a request for info on X/Open's XTI API
- standard. I apologize for the delay in posting this, but we
- have other deadlines. The responses were not as plentiful
- as I had hoped, but the few I did receive were helpful. Many
- thanks to Joel Spencer of Bull Worldwide Information Systems,
- who was especially helpful.

- ( Joel Spencer faxed a copy of the DPX & DPX/2 reference manual
- appendix from BULL Info. Systems. The appendix briefly discusses
- the differences between XTI & TLI. Below is a short summary of
- the appendix, most of which I quoted. )
-
- XTI is based on the SVID Issue 2, Volume 3, Networking
- Services Extensions. XTI provides refinement of the Transport
- Level Interface where such refinement is considered necessary.
- This refinement includes:
- - additional commentary ...
- - modifications to the interface ...
- - removal of dependencies on specific UNIX verisons ...
-
- The following features can be considered XTI extensions to TLI:
- - Some functions may return more error types ...
- - transport provider identifier has been generalised ...
- - additional events have been defined ...
- - additional features added to t_snd(), t_sndrel(), t_rcvrel()
- - can use options for certain types of transport service
- - O_RDONLY & O_WRONLY flags usage withdrawn
- - XTI checks value of 'qlen' and prevents applications
- waiting forever on 't_listen()' calls
-
- ( Joel also answered a few questions, which I included the responses to. )

- One piece of information for you. The TLI interface is in fact a product of
- AT&T and not OSF. It is what X/Open based XTI (which OSF supports) on.

-
- XTI is described in voume 7 of the X/Open Portability Guide, issue 3 (XPG3).
- The ISBN number is 0-13-685892-9. You can walk into any decent bookstore
- and have them order it (it is published by Prentice Hall). Or you can go
- to a computer-specialist bookstore and ask them if they have it in stock.
-
- It is supposed to be a transport-level independant networking interface
- (You are supposed to be able to write apps that will work over both
- ISO and TCP/IP stacks, not caring which one is used).
-
- You might want to contact X/Open directly to see if they have published
- anything on XTI since XPG3 came out.
