posix

Hi,

I'm trying to extract a string from another using regex. I'm using the POSIX regex functions (regcomp, regexec ...), and I fail at capturing a group ...

For instance, let the pattern be something as simple as "MAIL FROM:<(.*)>"
(with REG_EXTENDED cflags)

I want to capture everything between '<' and '>'

My problem is that regmatch_t gives me the boundaries of the whole pattern (MAIL FROM:<...>) instead of just what's between the parenthesis ...

What am I missing ?

Thanks in advance,
