The var parameter generation suggests it is old, original API generation

Maybe the type changed in MSDN over time. Some things got flipped when 
the win9x and winnt winapi implementations were synchronized.

Please file a bug, and I'll add a correct overload (with int and without 
VAR param etc), and move this declaration to legacy
