    struct strscanner *p;

    GET_SCANNER(self, p);
    if (! MATCHED_P(p)) return Qnil;

                         adjust_register_position(p, p->regs.beg[0]),
                         adjust_register_position(p, p->regs.end[0]));

scanner = StringScanner.new('foobarbaz')
scanner.matched        # => nil
scanner.pos = 3

scanner.match?(/nope/) # => nil
scanner.matched        # => nil
