Specifies the pointer to the structure with job step request specification. See slurm.h for full details on the data structure's contents.
Specifies the double pointer to the structure to be created and filled with a description of the created job step: node allocation, credentials, etc. See slurm.h for full details on the data structure's contents.


slurm_free_job_step_create_response_msg Release the storage generated in response to a call of the function slurm_job_step_create.

slurm_job_step_create Initialize a job step including the allocation of nodes to it from those already allocate to that job. Always release the response message when no longer required using the function slurm_free_job_step_create_response_msg. The list of host names returned may be matched to their data in the proper order by using the functions hostlist_create, hostlist_shift, and hostlist_destroy.


On success, zero is returned. On error, -1 is returned, and Slurm error code is set appropriately.


SLURM_PROTOCOL_VERSION_ERROR Protocol version has changed, re-link your code.

ESLURM_INVALID_JOB_ID the requested job id does not exist.

ESLURM_ALREADY_DONE the specified job has already completed and can not be modified.

ESLURM_ACCESS_DENIED the requesting user lacks authorization for the requested action (e.g. trying to delete or modify another user's job).

ESLURM_DISABLED the ability to create a job step is currently disabled. This is indicative of the job being suspended. Retry the call as desired.

ESLURM_INTERCONNECT_FAILURE failed to configure the node interconnect.

ESLURM_BAD_DIST task distribution specification is invalid.

SLURM_PROTOCOL_SOCKET_IMPL_TIMEOUT Timeout in communicating with SLURM controller.


These functions are included in the libslurm library, which must be linked to your process for use (e.g. "cc -lslurm myprog.c").
