28  * svcs - display attributes of service instances
29  *
30  * We have two output formats and six instance selection mechanisms.  The
31  * primary output format is a line of attributes (selected by -o), possibly
32  * followed by process description lines (if -p is specified), for each
33  * instance selected.  The columns available to display are described by the
34  * struct column columns array.  The columns to actually display are kept in
35  * the opt_columns array as indicies into the columns array.  The selection
36  * mechanisms available for this format are service FMRIs (selects all child
37  * instances), instance FMRIs, instance FMRI glob patterns, instances with
38  * a certain restarter (-R), dependencies of instances (-d), and dependents of
39  * instances (-D).  Since the lines must be sorted (per -sS), we'll just stick
40  * each into a data structure and print them in order when we're done.  To
41  * avoid listing the same instance twice (when -d and -D aren't given), we'll
42  * use a hash table of FMRIs to record that we've listed (added to the tree)
43  * an instance.
44  *
45  * The secondary output format (-l "long") is a paragraph of text for the
46  * services or instances selected.  Not needing to be sorted, it's implemented
47  * by just calling print_detailed() for each FMRI given.
