NAME

       slurm_free_ctl_conf, slurm_load_ctl_conf, slurm_print_ctl_conf - Slurm information reporting functions

SYNTAX

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

       long slurm_api_version ();

       void slurm_free_ctl_conf (
            slurm_ctl_conf_t *conf_info_msg_ptr
       );

       int slurm_load_ctl_conf (
            time_t update_time,
            slurm_ctl_conf_t **conf_info_msg_pptr
       );

       void slurm_print_ctl_conf (
            FILE *out_file,
            slurm_ctl_conf_t *conf_info_msg_ptr
       );

ARGUMENTS

       conf_info_msg_pptr
              Specifies  the  double pointer to the structure to be created and filled with the time of the last
              configuration update and detailed configuration information.  Configuration  information  includes
              control  machine  names,  file  names, timer values, etc. See slurm.h for full details on the data
              structure's contents.

       conf_info_msg_ptr
              Specifies the pointer to the structure created by slurm_load_ctl_conf.

       out_file
              Specifies the file to print data to.

       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_api_version Return the Slurm API version number.

       slurm_free_ctl_conf Release the storage generated by the slurm_load_ctl_conf function.

       slurm_load_ctl_conf Returns a slurm_ctl_conf_t that contains Slurm configuration records.

       slurm_print_ctl_conf Prints the  contents  of  the  data  structure  loaded  by  the  slurm_load_ctl_conf
       function.

RETURN VALUE

       For  slurm_api_version  the  Slurm  API  version  number is returned.  All other functions return zero on
       success and -1 on error with the Slurm error code 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

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

       int main (int argc, char *argv[])
       {
            slurm_ctl_conf_t * conf_info_msg_ptr = NULL;
            long version = slurm_api_version();

            /* We can use the Slurm version number to determine how
             * API should be used */
            printf("slurm_api_version: %ld, %ld.%ld.%ld\n", version,
                 SLURM_VERSION_MAJOR(version),
                 SLURM_VERSION_MINOR(version),
                 SLURM_VERSION_MICRO(version));

            /* get and print some configuration information */
            if ( slurm_load_ctl_conf ((time_t) NULL,
                                      &conf_info_msg_ptr ) ) {
                 slurm_perror ("slurm_load_ctl_conf error");
                 exit (1);
            }
            /* The easy way to print */
            slurm_print_ctl_conf (stdout,
                                  conf_info_msg_ptr);

            /* The hard way */
            printf ("control_machine = %s\n",
                    conf_info_msg_ptr->control_machine);
            printf ("first_job_id = %u\n",
                    conf_info_msg_ptr->first_job_id);

            slurm_free_ctl_conf (conf_info_msg_ptr);
            exit (0);
       }

NOTE

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