loadable plugin architecture for g++

[Jenny]

I am writing a program which may dynamically load *.so files as
plugin. I was looking libltdl and the one which is described here
http://www.belgeler.org/autobook/autobook-A-Simple-GNU-Linux-Module-Loader.html.
My problem is that I need to pass a object to the loaded module, but
it seems I can only pass char* as the parameter to the module whith
these APIs. Is there any other API which may let me do something like
this?
I was thinking about using SystemV share memory to do this, but the
same problem, I don't think it is suitable to handle the object with
complex data.

You're in a wrong newsgroup. comp.lang.c++ does not concern itself
with dynamic modules simply because the language doesn't have any
definition of them. The object model of C++ assumes that there is
only one program running in a sequential manner. No processes, no
shared memory, no threads, no nothing. All that is defined at the
OS level, so you need to post your query to a newsgroup that deals
with your OS.
