int old_errno;

old_errno = *allegro_errno; /* save state */
errno = *allegro_errno = 0; /* clear state */

do {
   replace_filename(buf, name, info.name, sizeof(buf));
   (*callback)(buf, info.attrib, param);

   if (*allegro_errno)
      break;

   c++;
} while (!al_findnext(&info));

errno = *allegro_errno = old_errno; /* restore old state */
