Any more exact ideas? All delegates take the Archive instance as their
first parameter and userdata as their second:
public delegate off_t SkipCallback (Archive archive, void* client_data,
off_t request);
Now, one method of Read (a sublcass of Archive) is:
public Result open (void* client_data, OpenCallback ocb, ReadCallback rcb,
CloseCallback ccb);
And "client_data" shall be passed to all callbacks.
I want have the delegate be:
public delegate off_t SkipCallback (off_t request);
and the method:
public Result open (OpenCallback ocb, ReadCallback rcb, CloseCallback ccb);
How should I do this?
