code for *.mp3 masking stuff

You know when you search for a file using something like *.mp3 or whatever, does anyone have any code that will determine if a particular string matches a particular mask?

This is (presumably) OS specific. You'll need to tell us what OS you're using...

Im using Windows...

Hmmm, not quite what I had in mind. More like this...

Code:

---

string fname = "Eine Kleine Nachtmusik.mp3", mask = "*ee*ven*.mp?";
if (DoesFilenameMatchMask(fname, mask))
  cout << "We have a match" << endl;
else
  cout << "No match" << endl;

---

Basically I need an implementation for 'DoesFilenameMatchMask'. I'd write one myself but im kinda busy with other stuff right now and its implementation seemed like it would be kinda involved.

Unfortunately none of those pages seemed to actually have the source code on them... so I ended up writing my own

Here it is if anyone wants it. If anyone has a more efficient implementation i'd like to see it

Code:

---

bool MatchMask(const char *str, const char *mask)
{
  char c;
  const char *p;

  while (*mask) {
    c = *mask++;

    if (c == '*') {
      while (*mask == '*' && *mask)
        mask++;

      if (*mask) {
        p = str;
        while (*p) {
          while (*p && *p != *mask)
            p++;
          if (MatchMask(p, mask)) return true;
          p++;
        }
      }
      else
        return true;
    }
    else if (c == '?') {
      if (!*str)
        return false;
    }
    else if (c != *str) {
      return false;
    }
    str++;
  }
  return !*mask && !*str;
}
