              Specifies the pointer to the structure created by slurm_load_front_end.

              Specifies  the  double  pointer  to the structure to be created and filled with the
              time of the last front end node update, a record count,  and  detailed  information
              about  each front_end node. Detailed front_end node information is written to fixed
              sized records and includes: name, state, etc.  See slurm.h for full details on  the
              data structure's contents.

              Specifies   a   pointer   to   a   single   front   end   node   record   from  the
              front_end_info_msg_ptr data structure.

              Print one record per line if non-zero.

              Specifies the file to print data to.

              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


       slurm_free_front_end_info_msg  Release  the  storage generated by the slurm_load_front_end

       slurm_load_front_end Returns a ont_end_info_msg_t that contains  an  update  time,  record
       count, and array of records for all front end nodes.

       slurm_print_front_end_info_msg  Prints  the  contents of the data structure describing all
       front end node records from the data loaded by the slurm_load_front_end function.

       slurm_print_front_end_table Prints to a file the contents of the data structure describing
       a single front end node record loaded by the slurm_load_front_end function.

       slurm_psrint_front_end_table   Prints  to  memory  the  contents  of  the  data  structure
       describing a single front end node record loaded by the slurm_load_front_end function.


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

       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.
