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. Only information about partitions on the local cluster will be
returned unless the cluster is in a federation and the SHOW_ALL flag is set.

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.
