提取定义语句.cpp

ns2的tcl脚本的解析器,能够解析简单的有限网络下的tcl脚本,并保存为.data文件

#include <stdio.h>

extern struct buffer *now;
extern struct buffer *head;

//补全完整定义
void fillsente(FILE *fp)
{
	char word[20];
	char *ch;
	word[0]='\0';
	ch=(char *)malloc(sizeof(char));
	*ch=fgetc(fp);
	count=0;
	while(count<5)
	{
		*ch=pre_getting(ch,fp);
		getword (fp,word,ch);
		ins_save(word);
	}
}

//提取定义，入口是搜索模块的结果+文件指针
struct buffer *gather(int flag,FILE *fp)
{
	struct buffer *defi;
	if (flag==1)return(head->next);
	else defi=now;
	fillsente(fp);
	return(defi);
