Funny the regex information should come up, at so timely a point in what
I'm working on :) I've read the man pages on regex recently and, in the
absence of any working examples, decided to shelf it for another time. Lo
and behold, an exaple to go from... Thanks Daniel!
I do have a question on the Mailer Code(tm) you included... In the area
where you're compiling the expression, the first parameter to regcomp() is
your expression plus an offset i. You don't have a local i defined, though
you do have idx. However, you aren't using it anywhere beyond
initialization to 0. Am I correct in assuming that idx should be
incremented by 1 after each successful call to regcomp()?
Thanks for your input....
