NAME

       slurm_hostlist_create, slurm_hostlist_shift, slurm_hostlist_destroy - Slurm host list support functions

SYNTAX

       #include <slurm/slurm.h>

       hostlist_t slurm_hostlist_create (
            char *node_list
       );

       char * slurm_hostlist_shift (
            hostlist_t host_list
       );

       void slurm_hostlist_destroy (
            hostlist_t host_list
       );

ARGUMENTS

       node_list
              A list of nodes as returned by the slurm_job_step_create functions. The returned value may include
              a simple range format to describe numeric ranges of values and/or multiple  numeric  values  (e.g.
              "linux[1-3,6]" represents "linux1", "linux2", "linux3", and "linux6").

       host_list
              A hostlist created by the slurm_hostlist_create function.

DESCRIPTION

       slurm_hostlist_create  creates  a  database  of node names from a range format describing node names. Use
       slurm_hostlist_destroy to release storage associated with the database when no longer required.

       slurm_hostlist_shift  extracts  the  first  entry  from  the  host   list   database   created   by   the
       slurm_hostlist_create function.

       slurm_hostlist_destroy  releases storage associated with a database created by slurm_hostlist_create when
       no longer required.

RETURN VALUE

       slurm_hostlist_create returns the host list database or NULL if memory  can  not  be  allocated  for  the
       database.

       slurm_hostlist_shift returns a character string or NULL if no entries remain in the database.

EXAMPLE

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

       int main (int argc, char *argv[])
       {
            hostlist_t my_hostlist;
            char *hostnames, *host;

            /* generate a list of hostnames, possibly using a */
            /*    slurm job step creation function */

            my_hostlist = slurm_hostlist_create (hostnames);
            if (my_hostlist == NULL) {
                 fprintf (stderr, "No memory\n");
                 exit (1);
            }

            while ( (host = slurm_hostlist_shift(my_hostlist)) )
                 printf ("host = %s\n", host);

            slurm_hostlist_destroy (my_hostlist) ;
            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").
