SYNTAX

       #include <stdio.h>
       #include <slurm/slurm.h>

       void slurm_free_job_step_info_response_msg (
            job_step_info_response_msg_t *job_step_info_msg_ptr
       );

       void slurm_get_job_steps (
            time_t *update_time,
            uint32_t job_id,
            uint32_t step_id,
            job_step_info_response_msg_t **job_step_info_msg_pptr,
            uint16_t show_flags
       );

       void slurm_print_job_step_info (
            FILE *out_file,
            job_step_info_t *job_step_ptr,
            int one_liner
       );

       void slurm_print_job_step_info_msg (
            FILE *out_file,
            job_step_info_response_msg_t *job_step_info_msg_ptr,
            int one_liner
       );

ARGUMENTS

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

job_step_info_msg_pptr
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.

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

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

one_liner
Print one record per line if non-zero.

out_file
Specifies the file to print data to.

show_flags
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.

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

update_time
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
returned.

DESCRIPTION

       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
       specified.

       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.

RETURN VALUE

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

ERRORS

       SLURM_NO_CHANGE_IN_DATA Data has not changed since update_time.

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

       SLURM_PROTOCOL_SOCKET_IMPL_TIMEOUT Timeout in communicating with SLURM controller.

EXAMPLE

                    step_info_ptr->last_update,

                 printf ("JobId=%u StepId=%u\n",
                      step_info_ptr->job_steps[i].job_id,
                      step_info_ptr->job_steps[i].step_id);
            }

            slurm_free_job_step_info_response_msg(step_info_ptr);
            exit (0);
       }

NOTES

       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.
