问题描述
我正在尝试理解一些代码,并且遇到了一个我从未见过的关键字.我试图用Google搜索它,但也没有找到任何有关它的信息.
I am trying to understand some code and I've come across a keyword that I've never seen before. I tried to google it, but haven't found anything regarding it as well.
char *valtext;
#line 1 "Values.l"
#define INITIAL 0
#line 2 "Values.l"
int reserve(char *s);
#line 388 "lex.val.c"
我已经包含了整个代码块,希望也许有人可以帮助我理解这段代码.我的系统上找不到任何名为"Values.l"的文件,而这部分代码位于"lex.val.c"文件中.
I've included the entire block hoping that perhaps someone can help me understand this chunk of code. I can't find any files on my system named "Values.l" and this chunk of code is located in the "lex.val.c" file.
提前谢谢.
