Sure! I'm going to use that mymod example.
1. Start emacs 26.3 with:
"~/programs/emacs/emacs-26.3/src/emacs -Q"
2. Run in *scratch* (or minibuffer):
(load "/home/sanel/programs/emacs/module-test/mymod.so")
Loading without ".so" extesions also works.
3. This will return 't'.
4. After mymod.so is loaded, 'mymod-test' function should be defined.
5. In *scratch* or minibuffer, running: (fboundp 'mymod-test) => nil.
Also, evaliuating '(mymod-test)' will throw this error:
Debugger entered--Lisp error: (void-function mymod-test)
(mymod-test)
eval((mymod-test) nil)
elisp--eval-last-sexp(t)
eval-last-sexp(t)
eval-print-last-sexp(nil)
funcall-interactively(eval-print-last-sexp nil)
call-interactively(eval-print-last-sexp nil nil)
command-execute(eval-print-last-sexp)
Replicating the same steps in emacs 27.2, in the step 4. it will
return 't' and when '(mymod-test)' is called, it will return 42.
