If a structure member is empty there is no need to define it. It's
probably defined on the native side in order to perform some address/

Hello,
A function's parameter is a struct that contains another struct as its
member. This member struct is an empty one, containing no members.
At initalization of the corresponding Structure object I get this:
java.lang.IllegalArgumentException: Can't determine size of
nested structure: Structure class hu.tinca.jburn.lib.Libburn

How can I use such an empty struct?
