char *node_list |

char * slurm_hostlist_shift (

void slurm_hostlist_destroy (

);
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.
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.
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.
