token.h

一个编译器修改的例子

#ifndef TOKEN_H
#define TOKEN_H

typedef struct token
{
    char	*name;
    char	*file_name;
    unsigned	line_number;
}
Token;

Token	*new_token(void);
		/* Create a new 'Token' structure. This copies the current
		 * value of yytext into (and thus allocates memory for)
		 * token->name, and sets token->line_number to current_line.
		 * (see lex.h)
		 */
void	delete_token(Token *);
