By default, Windows uses stdcall calling convention when calling 
externally defined subroutines in dynamic link libraries. It depends 
also if the dynamic link library uses stdcall calling convention, too.
Other platforms uses cdecl (unix/linux et al).

In your case it may be pascal default one calling convetion.
