Regexp in C - match group

Question

I\'ve been struggling with regular expressions in C (just /usr/include/regex.h).

---

I have (let\'s say) hundreds of regexps and one of them can match

Answer 1

You could have them give you a array of strings that contain your regexps and test each one of them.

//count is the number of regexps provided
int give_me_number_of_regex_group(const char *needle,const char** regexps, int count ){
  for(int i = 0; i < count; ++i){
    if(regex_match(needle, regexp[i])){
      return i;
    }
  }
  return -1; //didn't match any
}

or am i overseeing something?
