| | | | | | Now that we use utmpx, we more often have entries for which the ut_line is left blank. To prevent us from returning struct stat for "/dev/", check that the resulting stat structure belongs to a character device.

* Port w(1) to utmpx.ed2010-01-131-5/+6
| | | | | | | | | Let it print "-" when the TTY string is empty. In this case, it must also make sure it doesn't match processes who also have no controlling TTY. Otherwise it will print random kernel processes when trying to pick the best matching process. Eventually it should look at the value of ut_pid as well.

* Let w(1) use utmpx.ed2009-12-061-29/+26
| | | | | | | | | | We don't have UT_*SIZE anymore. One of the reasons for that is because all strings are null terminated, there is no need for apps to copy strings out of the utmpx structure. This means we can define W_DISP*SIZE lengths for all columns. While there, adjust the sizes a little. Steal some bytes from the username column, while extending the hostname column quite a bit.

Use realhostname_sa() to resolve addresses (the old code was wrong). Rename ``x'' to ``x_suffix'' to avoid confusion. Hard code the host column width to 16 (against the imminent increase of UT_HOSTSIZE in utmp.h).

* Change the proc information returned from the kernel so that itmckusick2000-12-121-13/+9
| | | | | | | | | | | | no longer contains kernel specific data structures, but rather only scalar values and structures that are already part of the kernel/user interface, specifically rusage and rtprio. It no longer contains proc, session, pcred, ucred, procsig, vmspace, pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If any of these changed in size, ps, w, fstat, gcore, systat, and top would all stop working. The new structure has over 200 bytes of unassigned space for future values to be added, yet is nearly 100 bytes smaller per entry than the structure that it replaced.

A couple of nits: - spelling/typo fix. - some of the easier style(9) fixes where it was bothering me. - Handle 100+ days idle time (ha!). Probably the right thing to do is to do a snprintf into a buffer and strlen the result rather than doing hackery on magic numbers. XXX the wide (and mostly unused) username and tty columns annoy me since it it could be used for more useful information for the command. We should actually count the largest username and tty and adjust like 'ls -l' does.
