S1E2课后作业里面出现了“对’Istat‘未定义的引用”
在完成 S1E2课后作业的时候出现了如下问题……不知道怎么回事呃 抄写的代码如下
#include <stdio.h>
#include <unistd.h>
#include <dirent.h>
#include <string.h>
#include <stdlib.h>
#include <sys/stat.h>
#define MAX 256
long total;
int countLines(const char *filename);
int isCode(const char *filename);
void findALLDirs(const char *path);
int countLines(const char *filename)
{
FILE *fp;
int count = 0;
int temp;
if ((fp = fopen(filename,"r")) == NULL)
{
fprintf(stderr,"Can not open the file:%s\n",filename);
return 0;
}
while ((temp = fgetc(fp)) != EOF)
{
if (temp == '\n')
{
count++;
}
}
fclose(fp);
return count;
}
int isCode(const char *filename)
{
int length;
length = strlen(filename);
if(!strcmp(filename + (length - 2),".c"))
{
return 1;
}
else
{
return 0;
}
}
void findALLDirs(const char *path)
{
DIR *dp;
struct dirent *entry;
struct stat statbuf;
if ((dp = opendir(path)) == NULL)
{
fprintf(stderr,"The path %s is wrong!\n",path);
return;
}
chdir(path);
while ((entry = readdir(dp)) != NULL)
{
Istat(entry->d_name,&statbuf);
if(!strcmp(".",entry->d_name) || !strcmp("..", entry->d_name))
continue;
if(S_ISDIR(statbuf.st_mode))
{
findALLDirs(entry->d_name);
}
else
{
if (isCode(entry->d_name))
{
total += countLines(entry->d_name);
}
}
}
chdir("..");
closedir(dp);
}
int main()
{
char path = ".";
printf("计算中...\n");
findALLDirs(path);
printf("目前你总共写了%ld行代码!\n\n",total);
return 0;
} lstat(entry->d_name,&statbuf);
