PointerByReference should work, if the intent is to return a pointer
into a by-reference argument. From there you can extract different
types from the returned pointer, or treat it as an opaque object.

The library I'm trying to map to is Graphviz. To render an graph,
there are three methods[1]: gvRender, gvRenderData, and
gvRenderFilename. I was able to get gvRenderFilename to work using
JNA, but I'm looking for a way to not write the file to disk. May be
gvRenderData would work, but my C programming abilities are failing me
and I'm not sure what to pass in for the "char ** result" argument in
C or Java via JNA.

I want to render an image to an java.io.OutputStream. I want to
use a
C library to render that image and the function looks like:
render(File *out);
Any ideas how this might be accomplished? Must the image be rendered
to a file system in C and then read in Java once complete? Is there
any way to not write it to disk first?
cheers,
