Function FindAllFilesSize

Descent3/pilot.cpp:2290–2311

FindAllFilesSize Looks in the current directory and returns the number of bytes of memory that will be needed for a buffer of filenames (see FindAllFiles()). pattern = wildcard pattern to match filecount = will be filled in with the number of files it finds

//	pattern	=	wildcard pattern to match
//	filecount =	will be filled in with the number of files it finds
int FindAllFilesSize(const char *pattern, int *filecount) {
  if (!pattern) {
    *filecount = 0;
    return 0;
  }

  char filename[_MAX_PATH];
  int size = 0;
  int count = 0;

  if (ddio_FindFileStart(pattern, filename)) {
    count++;
    size += strlen(filename) + 1;
    while (ddio_FindNextFile(filename)) {
      count++;
      size += strlen(filename) + 1;
    }
    ddio_FindFileClose();
  }
  *filecount = count;
  return size;
}
