- Thread-topic: Callback from NKE
After some further research, and I don't know if this is more a Unix question than an Apple question, but what about using socreate, to assign a call back function in the Client with some defined intercepts from the kernel. I know this is done within the kernel, for system events and etc., but can it also be done in the userland?
To eliminate the loop on recv()
Thanks

Yes, both select() and the CFSocket stuff are user-mode APIs.
I don't know of any CF* documentation other than what is available at
Apple's developer website (there may be other info out there), but for
select(), there are several books that give a great intro to the use of
select() and other BSD-style low-level APIs. Notable among them is W.
Richard Stevens's "Unix Network Programming" (v. 1, 2nd ed). There is
a third edition by a different author, and I'm not familiar with that.
The Stevens website has some details plus a tarball of a bunch of
example code that goes with the book (<http:www.kohala.com>).
Stevens also has a book called "Advanced Programming in the Unix
Environment" that is worth having (plus code on the site). He was an
excellent expositor.

Justin
