How to do regex string replacements in pure C?

Question

I\'ve looked at the regex functions in the POSIX regex library and the PCRE library, but both of them don\'t seem to have a string replacement function. I don\'t want to use

Answer 1

The PCRE library itself does not provide a replace function, but there is a wrapper function available at the PCRE downloads page that accepts perl style =~ s/pattern/replace/ syntax and then uses the PCRE native functions to do a substitute/replace for you. Go to http://www.pcre.org/ then click on the Download link: ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/, then the Contrib directory. The package/project you want is: pcrs-0.0.3-src.tar.gz.

Note that I have not used this myself so I cannot testify as to how well it works. It is a fairly small and simple piece of code however, so it may well serve your purpose nicely.
