Get list of file

Hello,

Is there a function that return all file in directory ???
I need the name of all files in one directory.

thanks to help me.

There is no C++ standard function for this operation. Depends on OS. If you are using Windows use FindFirstFile and FindNextFile API functions. If you are using Windows with MFC try the CfileFind class.

Regards,

As mentioned there is no platform independent way...

For a windows system you can use the following...The following sample does a search for all .avi-files on drive c:\.

Code:

---

#include <string>
#include <vector>
#include <iostream>

#include <conio.h>

using std::cout;
using std::endl;
using std::string;
using std::vector;

int SearchDirectory(vector<string> &refvecFiles,
                    const string  &refcstrRootDirectory,
                    const string  &refcstrExtension)
{
  string          strFilePath;            // Filepath
  string          strPattern;              // Pattern
  HANDLE          hFile;                  // Handle to file
  WIN32_FIND_DATA FileInformation;        // File information


  strPattern = refcstrRootDirectory + "\\*." + refcstrExtension;

  hFile = ::FindFirstFile(strPattern.c_str(), &FileInformation);
  if(hFile != INVALID_HANDLE_VALUE)
  {
    do
    {
      if(FileInformation.cFileName&#091;0&#093; != '.')
      {
        strFilePath.erase();
        strFilePath = refcstrRootDirectory + "\\" + FileInformation.cFileName;

        if(FileInformation.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
        {
          // Search subdirectory
          int iRC = SearchDirectory(refvecFiles, strFilePath, refcstrExtension);
          if(iRC)
            return iRC;
        }
        else
        {
          // Save filename
          refvecFiles.push_back(strFilePath);
        }
      }
    } while(::FindNextFile(hFile, &FileInformation) == TRUE);

    // Close handle
    ::FindClose(hFile);

    DWORD dwError = ::GetLastError();
    if(dwError != ERROR_NO_MORE_FILES)
      return dwError;
  }

  return 0;
}

int main()
{
  vector<string> vecFiles;

  // Search 'c:' for '.avi' files
  int iRC = SearchDirectory(vecFiles, "c:", "avi");
  if(iRC)
  {
    cout << "Error " << iRC << endl;
    return -1;
  }

  // Print results
  for(vector<string>::iterator iter = vecFiles.begin();
      iter != vecFiles.end();
      ++iter)
    cout << *iter << endl;

  // Wait for keystroke
  _getch();

  return 0;
}
