linux下目录操作

1. 常用函数

#include <dirent.h>

//open a directory

//failed-NULL, other-return a DIR stream

DIR *opendir (const char* path_name);

//close the directory stream

//0 succeed, -1 not

int closedir(DIR* dir_ptr);

//read a dir entry from dir_ptr

//NULL for EOF or error

dirent* readdir(DIR* dir_ptr);

2.实例

读取当前目录下的普通文件

#include <dirent.h>

#include <iostream>

using namespace std;

int main()

{

    DIR* dir_ptr = NULL;

    dirent* entry = NULL;

    dir_ptr = opendir("./");

    if (NULL == dir_ptr)

    {

        return -1;

    }   

    while (NULL != (entry = readdir(dir_ptr)))

    {

        if (entry->d_type != DT_DIR)

        {

            cout << "get a file:" << entry->d_name << endl;

        }

    }   

    closedir(dir_ptr);

    return 1;

}
