gboolean
predicate_func (gpointer key, gpointer value, gpointer userdata)
{
        gpointer  *p_key = (gpointer*)userdata;

        if (... value matches what you're looking for ...)
        {
                *p_key = key;
                return TRUE;
        }

        return FALSE;
}

   gpointer  value, key;

   value = g_hash_table_find (ht, predicate_func, &key);


Pass a struct if the predicate function needs more than one user data 
argument.
