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;
}

YEAh this code is the sh*t. And his code does make more sense if you are able to think outsdie the box rather than whien about no recursion. The fact of the matter is that if his solution is better than you should use it, thats the whole point of a polymorphic language. And if you dont understand pointers enough to pass null pointers into functions, well... maybe you should... rewrite the code so it checks for pointers?

I am but a lowly highschool student, but i've been coding since i was 7. And anyways, if you want to know what kind of program would require intense wildcard comparing, well, I wrote a program that auto-comments a source code file using a wildcard scheme, basically checks each line based on wildcard queries it loads up from a file and if the test is successful it inserts that comment at the end of that line. Pretty mindless commenting, but its just cause i'm sick of commenting my CS homework. So yeah, Jack Handy is the man.
