The problem of dynamic linking and loading is an old one.
It is a well-solved problem.
The question of "what do I need to do it?" is indeed the proper one.

I would remond your search begin at the "classical" manual that talks
about the system that first did effective, well-done, dynamic linking.

This is the Multics system, and the manual I would recommend for
you is the Multics Programmer's Reference Manual, Order Number
AG91.  In the back, it has the complete data-structure definitions
(in PL/1, but you can translate) for what you need.  It includes
about 65 different data-types; you can easily extend it as you need.

This can be ordered through your "Bull" representative I'm told.
It might not be possible, since Multics was discontinued,
but it's where I would start.
