I'll note that existing ioctl man pages don't have an explicit
statement that a libc is required --- nor do we do this for open(2),
stat(2), etc.   (And that's especially necessary for stat(2), BTW!)

Many of the ioctl man pages (or other system call man pages, for that
matter) also don't have an EXAMPLES section, either.

Perhaps it would be useful to have a discussion over what the
standards are for man pages in section 2, and when we need to state
things that seem to be rather obvious (like "you must have a C
library") and when there should be things like an EXAMPLES section?

Some the suggestions you are making don't seem to be adhered to by
the existing man pages, and more text is not always better.
