uPriority (USHORT)
The range is 1 through 9, with 1 being the highest queue priority.
The default job priority (DefJobPrio) is determined from:
DefJobPrio=100-(10* uPriority).
If a job is added with PRJ_NO_PRIORITY specified, DefJobPrio is used. If a default priority higher than the default job priority is specified, the default job priority is used. If a default priority lower than the default is specified, the specified job priority is used.
