DLL Error...

[compaqt]

VB based dll api syntex is as follows:

Function FSDKVB_GetCameraList( ByRef CameraList As Variant, ByRef CameraCount As Long ) As Long

How can I declare the DLL32 Function ..... for this API?

I tried:
DLL32 FUNCTION FSDKVB_GetCameraList( @aCameras AS PTR, @nCameras AS PTR ) AS LONG PASCAL LIB "facesdk-vb.dll"

but the program exits without any error at this point.
