Re: Integration with C
Hi Andrew,
I've read over the gcj documentation in try to find a logical way to
register a collection of function pointers. The only structure that I
can find is the gnu.gcj.RawData class which can contain anything but
need to be cast to the correct type explicitely. Is this a way to do
what I need, or am I overlooking something? It would be great to see
some examples of this, do you know if there are some available?
Thanks for the help,
Geert

Yes, function pointers are fine for calling CNI hooks. That was one
of the design goals. However, if you want to call a Java method
you'll have to get the address of the object somehow.
