Ioctl: the Swiss Army knife of system calls. I
thought it was a neat
idea when it arrived (much better then those primitive stty/gtty calls)
but now...
Like they say, when the only tool you have is a hammer...
Better syntax than stty/gtty, maybe but I'm not sure the semantics are that
much better. The problem is that, especially with devices, what the I/O
commands do is so widely varied that it's hard to fit them all under a
unified umbrella. Maybe some (e.g. asynchronous I/O), but not all.
