Wildcard string compare (globbing)

By , 15 Feb 2005
 

Usage:

This is a fast, lightweight, and simple pattern matching function.

if (wildcmp("bl?h.*", "blah.jpg")) {
  //we have a match!
} else {
  //no match =(
}

Function:

int wildcmp(const char *wild, const char *string) {
  // Written by Jack Handy - <A href="mailto:jakkhandy@hotmail.com">jakkhandy@hotmail.com</A>
  const char *cp = NULL, *mp = NULL;

  while ((*string) && (*wild != '*')) {
    if ((*wild != *string) && (*wild != '?')) {
      return 0;
    }
    wild++;
    string++;
  }

  while (*string) {
    if (*wild == '*') {
      if (!*++wild) {
        return 1;
      }
      mp = wild;
      cp = string+1;
    } else if ((*wild == *string) || (*wild == '?')) {
      wild++;
      string++;
    } else {
      wild = mp;
      string = cp++;
    }
  }

  while (*wild == '*') {
    wild++;
  }
  return !*wild;
}

Questionhelp required for wilcard matching * and #memberSaimaAsif23 Feb '12 - 23:56 
I read this article " ,its really amazing. I appreciate your efforts. I am student, I need help in defining the same kind of function according to my requirements. I hope, I 'll get good response.
 
Words are strings which are separated by dots. Two additional characters are also valid i.e:The *, which matches 1 word and the #, which matches 0..N words Example: *.stock.# matches the routing keys usd.stock and eur.stock.dsf but not stock.nasdaq.
 

Your help would be highly appreciated.
