This is, of course, correct.

But please remember that almost all modern code that uses callbacks and
function pointers use an extra parameter (often of type void *) to avoid
this.  GTK+ and Gnome do this /very/ well and are thus quite friendly to
both C and programming in the large.

I would myself of course prefer that local/nested procedures were a part
of the standard language but that's not how things are :/

(And real closures would be even better.  And a half-way decent type
system.  With inference.  And a pony.  And no Kaczynski twins.)
