expected_tokens()

int SlamParser::Parser::context::expected_tokens	(	symbol_kind_type	yyarg[],
		int	yyargn
	)		const

Put in YYARG at most YYARGN of the expected tokens, and return the number of tokens stored in YYARG. If YYARG is null, return the number of expected tokens (guaranteed to be less than YYNTOKENS).
