Someone asked for sample pfiles output for something like inetd, to see
how the 'filename' line looks for things other than regular files and
how socket-specific things are handled in output. The one reply there
was did not show all of this.
Of course this is easy to obtain, but as an additional data point, this
has various kinds of files/devices/sockets, so I have included it below.
This shows that socket-specific attributes, options and 'sockname: ...'
go on separate lines, between the general (stat) attributes and the
filename (if any). It would probably be in that style to put 'offset:'
onto a new line for seekable file attributes.
