Good patterns for a C/C++ plugin-based system?

Question

When developing a C/C++ (=2?) plugin based framework with shared objects/dynamic libraries that need to support live swapping what examples would be helpful to look at for i

Answer 1

If you are on POSIX, dlopen(), dlsym() and dlclose() are all you need.

See man dlsym for details and examples.

There is a good article about loading dynamic libraries, and plugin infrastructure is an example.

EDIT OP added Windows as requirement so this approach won't help since Windows isn't POSIX-compliant. However there are similar functions in WinAPI - see here.
