Iterating through all mounted volumes

NOTE The CommonPoint application system on a UNIX host recognizes all mounted volumes. Using TVolumesIterator in a UNIX environment returns a correct TVolume for each mounted volume.

Example::DisplayVolumes defines a member function that displays the name of each mounted volume. The code uses two functions, PrintText and PrintName, which do not appear in this sample.

  TVolume Example::DisplayVolumes () const
  {
      PrintText("Displaying all volume names...\n\n");
  
      // Create an iterator 
  
      TVolumesIterator volumeIterator;
  
      // Create a volume instance equal to the first volume that the iterator 
      // encounters, and remember that name.
  
      TVolume aVolume = volumesIterator.First;
  
      // keep iterating as long as there are volumes left to iterate through
  
      while (aVolume != TVolumesIterator::kEndOfIteration)
      {
          PrintName(aVolume.GetName());
          aVolume = volumesIterator.Next();
      }
  }
