I would imagine for shared libraries there must be some method for making
them multi-segment. I can see 2 shared libraries on my Visor that are
possibly multi-segmented, one of which is the Net Library(96K). It has a
libr and code segments. Another developer library (121K) has a libr and 3
code segments. Any ideas on how that works?
It is true that shared libraries can't access global variables, but you can
allocate a chunk of memory and associate it with your library for use as you
would globals. It is a little more work but the results are almost the same
as using globals.
