/*
 * ipmpstat -- display IPMP subsystem status.
 *
 * This utility makes extensive use of libipmp and IPMP sysevents to gather
 * and pretty-print the status of the IPMP subsystem.  All output formats
 * except for -p (probe) use libipmp to create a point-in-time snapshot of the
 * IPMP subsystem (unless the test-special -L flag is used), and then output
 * the contents of that snapshot in a user-specified manner.  Because the
 * output format and requested fields aren't known until run-time, three sets
 * of function pointers and two core data structures are used. Specifically:
 *
 *      * The ipmpstat_walker_t function pointers (walk_*) iterate through
 *	  all instances of a given IPMP object (group, interface, or address).
 *	  At most one ipmpstat_walker_t is used per ipmpstat invocation.
 *	  Since target information is included with the interface information,
 *	  both -i and -t use the interface walker (walk_if()).
 *
 *      * The ofmt_sfunc_t function pointers (sfunc_*) obtain a given value
 *	  for a given IPMP object.  Each ofmt_sfunc_t is passed a buffer to
 *	  write its result into, the buffer's size, and an ipmpstat_sfunc_arg_t
 *	  state structure.  The state structure consists of a pointer to the
 *	  IPMP object to obtain information from (sa_data), and an open libipmp
 *	  handle (sa_ih) which can be used to do additional libipmp queries, if
 *	  necessary (e.g., because the object does not have all of the needed
 *	  information).
 *
 *	* The ofmt_field_t arrays (*_fields[]) provide the supported fields for
 *	  a given output format, along with output formatting information
 *	  (e.g., field width) and a pointer to an ofmt_sfunc_t function that
 *	  can obtain the value for a given IPMP object.  One ofmt_field_t array
 *	  is used per ipmpstat invocation, and is passed to ofmt_open() (along
 *	  with the output fields and modes requested by the user) to create an
 *	  ofmt_t.
 *
 *      * The ofmt_t structure is a handle that tracks all information
 *        related to output formatting and is used by libinetutil`ofmt_print()
 *	  (indirectly through our local ofmt_output() utility routine) to
 *	  output a single line of information about the provided IPMP object.
 *
 *	* The ipmpstat_cbfunc_t function pointers (*_cbfunc) are called back
 *	  by the walkers.  They are used both internally to implement nested
 *	  walks, and by the ipmpstat output logic to provide the glue between
 *	  the IPMP object walkers and the ofmt_output() logic.  Usually, a
 *	  single line is output for each IPMP object, and thus ofmt_output()
 *	  can be directly invoked (see info_output_cbfunc()).  However, if
 *	  multiple lines need to be output, then a more complex cbfunc is
 *	  needed (see targinfo_output_cbfunc()).  At most one cbfunc is used
 *	  per ipmpstat invocation.
