This is probably the code *calling* the DLL. Nothing of any interest is
happening in this code, it seems like a wrapper class to functionality
existing somewhere else, so can't really say anything about this snippet.
The actual DLL (or whatever) can do just about anything - from simple
calculations to formatting your hard drive. Nothing is really validated
here one way or the other (nor should it actually be - no point in
validating variables when you don't see what is being done with the
variables).

What's the dll supposed to do?
