Interfacing to C code - Handle?

[OrlEngr]

I need to create a LabView Interface to the following  'C' Call ....

Have you guys ever worked with passing Windows Handlers? 

extern "C" bool WINAPI ConnectDevice(HANDLE  hnd, USHORT VendorID, USHORT ProductID);

I'm using Labview 6.1

A handle is a U32. Windows API functions require the stdcall calling convention, but I'm assuming it will work in your C case as well. Look here for more details (and note the links at the top of the page).
