How do I develop C++ code (maybe using (partially) IOStreams) to
physically 1) move a directory from one path in the filesytem to
another and 2) copy a directory from path in the filesystem to another?

I know how to copy files and move files, but directories are tougher. I
also need to pass a flag as a parameter which gives the option to copy
the directory recursively (assuming the parameter directory has
sub-entries (files and more directories) - else it becomes a no-op if
there are no more directories to descend.

class DirectoryHandler
{
  public:
  //ctor and dtor omiited for obvious reasons (brevity)

  int moveDirectory (const std::string& from, const std::string& to);
  int copyDirectory (const std::string& from, const std::string& to);

};

Thanks for any help

Standard C++ has no concept of directories, so there is
obviously no immediate support for this sort of thing.  In fact,
the solution I'd normally adopt is system(); the argument is
very system dependant, but then, any other solution would be as
well.
