Wildcard string compare (globbing)

Matches a string against a wildcard string such as "*.*" or "bl?h.*" etc. This is good for file globbing or to match hostmasks.

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;
}

Guru, You're a douche bag.

And all that null program stuff is bullsh*t. Obviously the best program is first the one that works in all cases, then the fastest, and then smallest. Pretty simple criteria, really not necessary to be argue about. And readabillity has nothing to do with it, unless you are considering it from the computers standpoint, which I think is covered in the first criteria, no?

And small unreadable snippets are far better than bloated newb fragments if they run faster. And who said anything about impress more? you can stop taking pot shots at jack handy now, just because hes a better programmer than you doesnt mean you should try to bust his chops. Maybe if you werent such a f***ing pussy you'd "get a hotter chick". Clearly Jack Handy is able to write code that accomplishes a task more efficiently than you can. Yet you still try criticize, and then you come back with this post full of big bold text about irrelevant points... Maybe if your post is partly in bold it will IMPRESS MORE. f***ing douche.
