List files

int dirExist(const char *dir){
  struct dirent *dirp;
  DIR *dp;
  cout << "Checking input for " << dir << endl;
  if((dp = opendir(dir))== NULL){
    return FALSE;
  }
  while ((dirp = readdir(dp)) != NULL){
    cout << dp << " ./tryWrite" << endl;
    ofstream testWrite("./tryWrite");
    if (testWrite.is_open()){
      cout << "Writing to " << dp << endl;
      testWrite << "Test writing do not delete!" ;
      testWrite.close();
      std::remove("./tryWrite");
      return TRUE;
    }
    else
      {
    return FALSE;
      }



    return TRUE;
  } 
}

Nogen der kan set fejlen i dette stykke kode?
Min mening ned koden var at den skulle kunne udskille mapper fra en en liste over filer/mapper i en anden mappe :p
