- STREAMS were obsolete as soon as they were corrupted from the researchy
- streams by AT&T in the mid-1980'2. The future UNIX networking
- programming model is not clear. The fastest network implementations
- are not STREAMS based, and of the the years STREAMS have more and more
- faithfully emulated sockets. However, the death of CSRG is not a good
- sign for sockets. On the other hand, if USL is fails to squash both
- the free and the cheap 386 versions of 4.3BSD, sockets will live
- forever.
-
- The support code for things like name resolution in SVR4.1 STREAMS is
- not pretty, consistent, or obviously usable. One of the mysteries of
- life is how people manage to get by with it.
-
- It is possible that a future version of IRIX that is more or less
- SVR4-like might have sockets with STREAMS module glue and other stuff
- to satisfy the needs of STREAMS based applications. SGI's TCP speed
- appears likely to survive the initial inclinations of those who would
- have had SGI jump onto the AT&T/Sun network bandwagon.
-
- I've no doubt the letter mentioned above was only trying to say that
- the STREAMS documents are no longer being published by SGI. That's
- news to me. Still, Prentice Hall prints them on nice paper with what I
- think are better bindings.

- P.S. Before you decide I'm a completely ignorant socket fanatic, note
- that I did the original port of SVR3 STREAMS to the SGI UNIX,
- including writing the STREAMS modules and modifying the tty drivers to
- make SGI tty's STREAMS based in 1986.
