The limitation here is that LV VIs don't by default have C entrypoints. If you have the professional version of LV, you can build a DLL with C entrypoints, and possibly with types that match the signature of the callback. Without the signature info, I can't tell you. But you also need a way of passing a function pointer. You can do this with a small wrapper DLL, or you might be able to directly call the Win32 LoadProcAddress, giving it the DLL and function name and passing the function pointer around as an int32.
