前端之家收集整理的这篇文章主要介绍了
centos中c遍历目录文件例子,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
以下是很有意思的c遍历文件目录的代码,值得回味:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <dirent.h>
#include <unistd.h>
int readFileList(char *basePath)
{
DIR *dir;
struct dirent *ptr;
char base[1000];
if ((dir=opendir(basePath)) == NULL)
{
perror("Open dir error...");
exit(1);
}
while ((ptr=readdir(dir)) != NULL)
{
if(strcmp(ptr->d_name,".")==0 || strcmp(ptr->d_name,"..")==0) ///current dir OR parrent dir
continue;
else if(ptr->d_type == 8) ///file
printf("d_name:%s/%s\n",basePath,ptr->d_name);
else if(ptr->d_type == 10) ///link file
printf("d_name:%s/%s\n",ptr->d_name);
else if(ptr->d_type == 4) ///dir
{
memset(base,'\0',sizeof(base));
strcpy(base,basePath);
strcat(base,"/");
strcat(base,ptr->d_name);
readFileList(base);
}
}
closedir(dir);
return 1;
}
int main(void)
{
DIR *dir;
char basePath[1000];
///get the current absoulte path
memset(basePath,sizeof(basePath));
getcwd(basePath,999);
printf("the current dir is : %s\n",basePath);
///get the file list
memset(basePath,sizeof(basePath));
strcpy(basePath,"./XL");
readFileList(basePath);
return 0;
}
