-create_work() creates a workunit. The arguments are similar to those of the utility program; some of the information is passed in the DB_WORKUNIT structure, namely the following fields:
-{{{
-name
-appid
-}}}
-The following may be passed either in the DB_WORKUNIT structure or in the workunit template file:
-{{{
-rsc_fpops_est
-rsc_fpops_bound
-rsc_memory_bound
-rsc_disk_bound
-batch
-delay_bound
-min_quorum
-target_nresults
-max_error_results
-max_total_results
-max_success_results
-}}}

+create_work() submits a job. The ''name'' and ''appid'' fields of the DB_WORKUNIT structure must always be initialized.
+Other job parameters may be passed either in the DB_WORKUNIT structure or in the input template file (the latter has priority).
