From what I glean from this you are talking about having the plugin .so
access symbols that are defined in the host. I know this is possible,
and you don't even have to link against any stub library. Check out the
-E or --export-dynamic option to gnu ld.
I don't know if this is a good idea, though. It feels kinda freaky.
Do you mean that the plugin should dlopen the
host? Wouldn't that
require some way to pass the path to the host program to the plugin (in
which case you might as well pass a function pointer directly)?
I mean the linker should do it. If you dynamically build the plugin
against a stub library and the host exports something with the same ABI, I
/think/ the plugin should have the host's version of the function in its
namespace.
