  22  * \brief Set up a pcmk__output_t, (optionally) cib_t, and
  23  *        (optionally) pcmk_scheduler_t for use in implementing
  24  *        public/private API function pairs
  25  *
  26  * \param[in,out] out       Where to store a \c pcmk__output_t object
  27  * \param[in,out] cib       Where to store a \c cib_t object
  28  *                          (may be \c NULL if a CIB is not needed)
  29  * \param[in,out] scheduler Where to store a \c pcmk_scheduler_t object
  30  *                          (may be \c NULL if a scheduler is not needed)
  31  * \param[in,out] xml       Where to write any result XML
  32  *
  33  * \note The \p cib and \p scheduler arguments will only be valid if there
  34  *       are no errors in this function.  However, \p out will always be
  35  *       valid unless there are errors setting it up so that other errors
  36  *       may still be reported.
