Members
hContext
The hardware context to change the priority band of.
priorityBand
The priority band value assigned to this context. Assigning a context to focus and realtime priority bands requires the calling process to have SE_INC_BASE_PRIORITY_NAME privilege.
realtimeBandPriorityLevel
When the context belongs to the realtime scheduling priority band, this value indicates the priority level (0...31) within the realtime band. For all other bands, this value is ignored.
inProcessPriority
The process wide priority value, relative to other contexts of the same priority within the same process. Values range from -7 to +7. The default in process priority value is zero.
quantum
The context quantum value in 100ns units, relative to other contexts of the same priority within the same process.
gracePeriodSamePriority
The grace period value in 100ns units when this context preempts another context of the same priority within the same process.
gracePeriodLowerPriority
The grace period value in 100ns units when this context preempts another context of a lower priority within the same process. gracePeriodLowerPriority is typically smaller than gracePeriodSamePriority.
