reading files in a folder

Hi All,
I want to read a several (2000) files in a folder. I did as follows,
class for Readdir,

Code:

---

class        Readdir
{
        private:
        string                dirName;
       
        public:
        Readdir ( const string& m) { dirName = m; }
        ~Readdir() {}
               
        void        readFiles() const;
};

---

member function coding,

Code:

---

#include <dirent.h>
#include <errno.h>

void        Readdir::readFiles () const
{
                DIR* dirp;
                string        buff;
                struct dirent* dp;
                dirp = opendir( dirName.c_str());
                if (!dirp)
                {
                        cout<< "Error: failure opening directory! " << endl;
                        exit(1);
                }
               
                errno = 0;
               
                ofstream output;
                output.open("driftdata/drift", ios::out);
               
                while((dp = readdir (dirp))!=NULL)
                {
                        if(strstr (dp->d_name, ".dat"))
                        {
                                ifstream input(dp->d_name);
                                int lineno=0;
                               
                                while(getline(input, buff))
                                {
                                        if((++lineno%25)==5)
                                        {
                                                if(lineno ==4055) break;
                                               
                                                output<<buff<<endl;
                                        }
                                }
                        }
                        if(errno)
                        {
                                cout << " Error :readdir () failure" << endl;
                                exit(1);
                        }
                }
       
        output.close();
        closedir (dirp);
       
}

---

main,

Code:

---


int main(void)
{
Readdir                myDir(".");
       
        myDir.readFiles();
return 0;
}

---

In this case, my coding is working in linux OS (gCC compiler). But I want to run the codes in Windows OS ( Visual Studio).
Please tell me how can I do the above task in Windows.
The main problem is <dirent.h> header file is available in windows.

Please suggest me a different way to read files in a folder.

Thanks a lot in advance.

Well on Windows systems you can use
FindFirstFile() FindNextFile() here is an example
http://msdn2.microsoft.com/en-us/library/aa365200.aspx

and check-out this in the codeguru faqs
"Windows SDK File System: How to search for files in a directory and subdirectories?"
http://www.codeguru.com/forum/showthread.php?t=312461

or you can use this alternatively

Thanks for your information.
I wonder much whether is there any way available for files reading independent of OS or Compiler. I expect an idea which can work for all compilers.

Please help me..

The boost filesystem library offers file/directory functions independent of OS and Compiler.
