Can someone explain this code?

What does that code actually *do*?

Stop the compiler from complaining about an unused argument.

Thanks,

Stephen

Somebody tried to work around "unused argument" warning?

That makes sense, except my compiled didn't warn even when I took it out
:-) Ah, well, thanks for clearifying.

It depends on the compiler you're using.. My recollection is that
it shows up at least w/ gcc and -Wall and/or -pedantic.
