$key->QueryKey($class, $subs, $vals)

Retrieves information about the current key and returns it to the named scalar variables. The key class is saved in the class variable (it will be the null string "" on Win95 since it doesn't use key classes). The number of subkeys is saved in the $sub variable, and the number of values in the current key is saved in $vals.
