Opening and closing files is such a routine that I want to write a class
that will handle the opening and closing of files, and I have already done
most of the work. My problems is when I want to get the file handle, I
don't know how to do this, exactly. Below is the part of the class that is
causing the problem

   class FileIO
   {
      public:
         // file modes
         ios::openmode RW_OPEN_BIN;
      private:
         std::fstream f;
         std::string file_name;
         ios::openmode mode;
         fileprot permission;
       
      public:
         FileIO();
         ~FileIO();

         //Setters
         bool setFileName( const std::string&); bool
         setMode(ios::openmode);
         bool setPermission(const fileprot);

         //Getters
         const char*    getFileName()   const {return file_name.c_str();}
         ios::openmode  getMode()       const {return mode;             }
         const fileprot getPermission() const {return permission;       }
         const std::fstream&  getFileHandle() { return f;               }


         bool Create()throw(FileIOEx);
        
   }; //File


FileIO::FileIO(){
   //Open an existing binary file for reading and writing RW_OPEN_BIN =
   std::ios::in | std::ios::out | std::ios::binary; mode = this->RW_OPEN;
}
FileIO::~FileIO(){
   if(f.is_open()){f.close();}
}
//Setters
bool FileIO::setFileName(const std::string& str){
   file_name = str;
   return false;
}
bool FileIO::setMode(ios::openmode m){
   mode = m;
   return false;
}
bool FileIO::setPermission(const fileprot per){
   permission = per;
   return false;
}
bool  FileIO::Create() throw(FileIOEx){
   f.open(this->getFileName(), this->getMode() ) return false;
}

int main(){
   FileIO fio;
   fio.setFileName("File");
   fio.setMode(RW_OPEN_BIN);
   fio.Create();
   std::fstream& f = fio.getFileHandle(); 
   f << "Need Help!" << std::endl; // Here is the problem!!!!!
   return 0;
}
Doe anyone know how to go about getting the file handle in this way?

Thanks in advance
