I'll just mention that the Unix philosophy says "(almost) everything you
need to do, you do by running another process that does it". The Windows
philosophy is "My process does everything".
When a Windows programmer goes Unix, they are usually (I know I was)
hesitant about running an external program "only to" shut down the
machine/install a module/eject the CD/whatever.
If that is the case, David, just do "system" (I prefer fork+exec - saves
on the intermediate shell, but maybe that's just renmants of my Windows
days talking) for that and be done.
If, on the other hand, you want to hack the process, then by all means,
read the sources for insmod (and also the relevant sources from the
kernel, to ballance things out).
As usual, more info would give you more of an answer.
