Hello,

is it correct to map a C function

C: int create_instance(INST_INIT *init, FDESC *fdesc);

- where INST_INIT is a typedef struct ... and - where FDESC is a typedef void *

to Java using JNA in that way:

Java: int create_instance(INST_INIT init, FDESC fdesc);

- where INST_INIT is a class that extends Structure with some public members and - where FDESC is a class that extends PointerByReference

I have expecially with FDESC some strange behaviours. Is FDESC (its a kind of "instance handle") correct mapped?

If you use a PointerByReference instance in the init function, your actual FDESC value will be in PointerByReference.getValue().
