Slurm API(3)						 Slurm host list support functions					      Slurm API(3)

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
");
		 exit (1);
	    }

	    while ( (host = slurm_hostlist_shift(my_hostlist)) )
		 printf ("host = %s
", 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").
