I'm using winstl_module and the function module::get_handle() isn't 
implemented!
It's a one liner, so I guess it's easy to forget... or is winstl_module not 
ready for public use yet?

BTW, I'd done one of these before, and had given it an extra function (extra 
as in "besides just loading/unloading"):

 template<typename FnType>
 bool get_fn(char const* fn_name, FnType& fn) const
 {
  assert(m_dll != NULL);

  fn = reinterpret_cast<FnType>(GetProcAddress(m_dll, fn_name));
  return (fn != NULL);
 }

So all you do is use:

  void (*run)() = NULL;

  if( updater.get_fn("run", run) )
   run();

Where run can be of any type... it's not that great but it saves you the 
typedef or the double typing when getting a function's address.

Fixed. Silly me, eh?

That's a nice idea.

This is now in winstl::module. I've also enhanced the class so that it 
can participate in copy construction, by ref-counting the underlying 
module (via GetModuleFileName and LoadLibrary).

This'll be in 1.8.3.

Great!
