I did not manage to find anything that mentioned
the parameters/arguments: You found materials that
I did not. What context(s) were they from?

"portable way": what range of portability? Even having
shared libraries is likely not universal to all C/C++
contexts. Windows .DLL's have a different mechanism
if I remember right. And so on.

But even for a narrower Unix/BSD/Linux context: as far
as I know the conventions are just local/ABI conventions
and the compiler does not drive which conventions are
used: the environment does something to impose the
environment's desired rules.

[I'm no expert on POSIX rules so there might be material
from that direction that I'm not aware of.]
