regexp confusion

[MD]

What do most of the experienced programmers here do when they
encounter a situation, constrained to a C programming env obviously,
where they could
use a regexp system?

I find the regcomp(), regexec(),system a little unwieldy, especially
when
dealing with user inputted expressions. Is there example code someone
can point
me to as a howto on dealing with regexp issues?

Allow me to jump in before the *real* zealots.

regcomp et al are part of the POSIX standard. In c.l.c parlance, this
means they are not standard C!

To the best of my knowledge, standard C has no functions for
manipulating regular expressions. I suggest you try
comp.programmer.unix, before you are shouted at.

The C Standard does not provide any real regular expression functionality,
the functions you referenced are part of the POSIX standard which is not
discussed here. You should post your question over at
comp.unix.programmer where this will be on-topic.

I am not sure what you mean by unwieldly, the functions are fairly
straight-forward. My personal preference is the pcre library (not part of
any standard) which implements powerful regex functionality of the Perl
language and is well documented. You can learn more at www.pcre.org.

In comp.lang.c, find one of the many libraries which implement regexes
in ISO C. There's no function in the Standard which implements them
directly, but it's quite possible to write some in nothing but ISO C.

Neither regcomp() nor regexec() are Standard. If they're POSIX, ask in
comp.unix.programmer.
