Thread: chdir()

i'm currently using chdir() in my program, and I got it to work...however... I don't know how to cd to the root directory, or how to cd up one directory for that matter....here's the code...

Code:

#include <iostream>
#include <stdlib.h>
#include <string>
#include <unistd.h>

void main()
{
        char cmd[100] = " ";
        char dir[100] = " ";
        char * pch;
        int cmdLength, cmdCounter;
        int dirCounter = 0;

        cout << "Please enter command: ";
        cin.getline(cmd, 100);

        while (strcmp (cmd, "exit") !=0)
        {
                if((cmd[0] == 'c') && (cmd[1] == 'd') && (cmd[2] == ' '))
                {
                        cout << "I'm here corey..." << endl;
                        cmdLength = strlen(cmd);
                        cout << cmdLength << endl;
                        for(cmdCounter=3; cmdCounter < cmdLength; cmdCounter++)
                        {
                                cout << dir[dirCounter];
                                dir[dirCounter] = cmd[cmdCounter];
                                dirCounter++;
                        }
                        chdir(dir);
                        cout << "Please enter command: ";
                        cin.getline(cmd,100);
                }
                else
                {
                        system (cmd);
                        cout << "Please enter command: ";
                        cin.getline(cmd,100);
                }
        }
        exit(1);
}
