public static class Guid.REFIID extends PointerType
REFIID is a pointer to an IID.

This type needs to be seperate from IID, as the REFIID can be passed in from external code, that does not allow writes to memory.

With the normal JNA behaviour a structure, that crosses the native<-%gt;Java border will be autowritten, which causes a fault when written. Observed was this behaviour in COM-Callbacks, which get the REFIID passed into Invoke-method.

So a IID can't be used directly, although the typedef of REFIID (from MSDN):

typedef IID* REFIID;

and the jna behaviour is described as:

"When a function requires a pointer to a struct, a Java Structure should be used."
