Reference variables in jawin?

Hello, This is my first post to the list. Anyway I am a newbie in both
JINI and Jawin development so bare with me.

This is my problem. I would like to call a C++ method from Jawin which
uses a reference pointer. How can I handle such thing?

This is how the C++ code looks like:
int cbAIn( int BoardNum, int Channel, int Range, unsigned short *DataValue );

My code:
FuncPtr cBA = new FuncPtr("cbw32.DLL", "cbAInScan");
memHandle = cBA.invoke(int BoardNum, int Channel, int Range, ???);

If someone could put me in the right direction I would be grateful.
