In the SUN world "select" and "the Berkeley sockets suite" are supposedly
emulated under the hood using TLI.

poll is supposedly used in implementing the "emulation" for select...

I guess I have always assumed that meant you could use them fairly
interchangeably.. Taking into account the differences in the api and
side-effects in various scenarios...

I've always preferred "select"... But I guess with TLI you get the added
benefit by way of some of Sys V extensions..

If you can get it I would start with Steven's original UNIX Network
Programming and then work into the multi-volume sets... He gives you a lot
of good information in one book... Later one he divides it into several...
$$$...LOL

Albeit some info in the old book is dated...
