I'm sorry Jason, but that's just nonsense. Of course I can write
a dlopen() function which is statically linked into my program and
which is different from the dynamic dlopen(), but which will provide
the same functionality. It's might be non-trivial%, but it's not impossible.
(No, I'm not volunteering. :)
% The non-trivial part being to get all the information from the
statically linked binary into tables that dlopen() can access.
This part will probably need some fiddling while linking.
