#include<dirent.h>

Question

when i am including (#include in visual studio 2005) this headerfile it is showing the error as (fatal error C1083: Cannot open include file: 'dirent.h': No such file or directory) i am new to C++ can anyone please provide me the solution for this error?

Answer 1

The error message says it all. The file does not exist or it is not in the correct directory. Check out this website. It includes a free implementation of dirent.h.

Answer 2

Try including just dir.h and if that doesn't work try io.h

#include <errno.h>
#include <iostream>
#include <io.h>
#include <time.h>
using namespace std;

bool canDelete(int timeCreate);

int main() {
    struct _finddata_t data;
    int handle;
    handle = _findfirst("test.txt", &data);

    if(handle == -1) {
        exit(1);
    }

    if(canDelete(data.time_create)) {
        cout << "Deleting file ...\n\n";
    } else {
        cout << "File ok.\n\n";
    }
}
/**
* @param: the time in seconds that the file was created.
* @return: true if the file was created more than 7 days, 
* false otherwise.
**/
bool canDelete(int time_create) {
    time_t seconds = time(NULL);
    int days = 7;
    int max_time = 60 * 60 * 24 * days;
    int time_passed = seconds - time_create;
    if(time_passed > max_time) {
        return true;
    } else {
        return false;
    }
}

Answer 3

You should add the directory where the file is located to the "additional include folders" in the Visual Studio project properties.

Answer 4

The file dirent.h is not a C++ Standard header file. As you are on Windows, you probably want to use the FindFirstFile and related functions, declared in windows.h
