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