Perform all trivial ports to utmpx for usr.bin/.

They were already converted to use libulog, so it's easy to convert them
to utmpx.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Let wall(1) use utmpx.

2009-12-05T20:22:26+00:00

Because our implementation guarantees the strings inside struct utmpx to
be null terminated, we don't need to copy everything out, which makes
the code nicer to read.

Also set WARNS to 6 and add $FreeBSD$ to keep SVN happy.

write(1) needs to strip off the leading /dev/ from the tty name for the

2007-11-12T20:02:21+00:00

current tty as returned from ttyname(3) so it can try to avoid writing to
the current tty if possible.  Previously, it did this by trimming off any
leading directory (effectively performing a basename(3) on the path
returned from ttyname(3)).  However, this chopped off too much of the path
for ttys who have directories in their name such as pts(4).  Instead, just
strip off the leading /dev/ from the path returned by ttyname(3).  This
fixes write(1) when using pts(4).
