       job_id Specifies a slurm job ID. A value of zero implies all jobs.

              Specifies the double pointer to the structure to be created  and  filled  with  the
              time  of  the last node update, a record count, and detailed information about each
              job step specified. Detailed job step information is written to fixed sized records
              and includes: job_id, step_id, node names, etc. See slurm.h for full details on the
              data structure's contents.

              Specifies the pointer to the structure created by the function slurm_get_job_steps.

              Specifies a pointer to a single job step records  from  the  job_step_info_msg_pptr
              data structure.

              Print one record per line if non-zero.

              Specifies the file to print data to.

              Job  filtering  flags, may be ORed.  Information about job steps in partitions that
              are configured as hidden and partitions that the user's group is unable to  utilize
              are  not  reported  by default.  The SHOW_ALL flag will cause information about job
              steps in all partitions to be displayed.

              Specifies a slurm job step ID. A value of zero implies all job steps.

              For all of the following informational calls, if update_time is equal to or greater
              than  the  last time changes where made to that information, new information is not
              returned.  Otherwise all the configuration. job, node,  or  partition  records  are


       slurm_free_job_step_info_response_msg    Release    the    storage    generated   by   the
       slurm_get_job_steps function.

       slurm_get_job_steps Loads into details about job steps  that  satisfy  the  job_id  and/or
       step_id  specifications  provided  if  the  data  has  been  updated since the update_time

       slurm_print_job_step_info Prints the contents of the data structure  describing  a  single
       job step records from the data loaded by the lurm_get_job_steps function.

       slurm_print_job_step_info_msg Prints the contents of the data structure describing all job
       step records loaded by the lurm_get_job_steps function.


       On success, zero is returned. On error, -1 is  returned,  and  Slurm  error  code  is  set

       SLURM_PROTOCOL_VERSION_ERROR Protocol version has changed, re-link your code.

       These functions are included in the libslurm library, which must be linked to your process
       for use (e.g. "cc -lslurm myprog.c").

       Some data  structures  contain  index  values  to  cross-reference  each  other.   If  the
       show_flags argument is not set to SHOW_ALL when getting this data, these index values will
       be invalid.

       The slurm_hostlist_ functions can be used to convert SLURM node list  expressions  into  a
       collection of individual node names.
