NAME

       slurm_free_partition_info_msg,      slurm_load_partitions,     slurm_print_partition_info,
       slurm_print_partition_info_msg - Slurm partition information reporting functions

SYNTAX

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

       void slurm_free_partition_info_msg (
            partition_info_msg_t *partition_info_msg_ptr
       );

       int slurm_load_partitions (
            time_t update_time,
            partition_info_msg_t **partition_info_msg_pptr,
            uint16_t show_flags
        );

       void slurm_print_partition_info (
            FILE *out_file,
            partition_info_t *partition_ptr,
            int one_liner
       );

       void slurm_print_partition_info_msg (
            FILE *out_file,
            partition_info_msg_t *partition_info_msg_ptr,
            int one_liner
       );

ARGUMENTS

       one_liner
              Print one record per line if non-zero.

       out_file
              Specifies the file to print data to.

       partition_info_msg_pptr
              Specifies the double pointer to the structure to be created  and  filled  with  the
              time  of  the last partition update, a record count, and detailed information about
              each partition. Detailed partition information is written to  fixed  sized  records
              and includes: name, state, job time limit, job size limit, node names, indexes into
              the node table, etc. In the case of indexes into the node table, this is  an  array
              of  integers  with  pairs  of  start and end index number into the node information
              records and the data is terminated with a value of -1. See slurm.h for full details
              on the data structure's contents.

       partition_info_msg_ptr
              Specifies the pointer to the structure created by slurm_load_partitions.

       show_flags
              Job filtering flags, may be ORed.  Information about 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 partitions to
              be displayed.

       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_partition_info_msg  Release  the storage generated by the slurm_load_partitions
       function.

       slurm_load_partitions Returns a partition_info_msg_t that contains an update time,  record
       count, and array of partition_table records for all partitions.

       slurm_print_partition_info  Prints  the contents of the data structure describing a single
       partition records from the data loaded by the slurm_load_partitions function.

       slurm_print_partition_info_msg Prints the contents of the data  structure  describing  all
       partition records loaded by the slurm_load_partitions 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

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

       int main (int argc, char *argv[])
       {
            int i;
            partition_info_msg_t *part_info_ptr = NULL;
            partition_info_t *part_ptr;

            /* get and dump some partition information */
            if (slurm_load_partitions((time_t)NULL,
                                      &part_info_ptr, SHOW_ALL)) {
                 slurm_perror ("slurm_load_partitions error");
                 exit (1);
            }

            /* The easy way to print... */
            slurm_print_partition_info_msg (stdout,
                                            part_info_ptr, 0);

            /* A harder way.. */
            for (i = 0; i < part_info_ptr->record_count; i++) {
                 part_ptr = &part_info_ptr->partition_array[i];
                 slurm_print_partition_info(stdout, part_ptr, 0);
            }

            /* The hardest way. */
            printf("Partitions updated at %lx, records=%d\n",
                   part_info_ptr->last_update,
                   part_info_ptr->record_count);
            for (i = 0; i < part_info_ptr->record_count; i++) {
                 printf ("PartitionName=%s Nodes=%s\n",
                      part_info_ptr->partition_array[i].name,
                      part_info_ptr->partition_array[i].nodes );
            }

            slurm_free_partition_info_msg (part_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.
