STOR_THREAD_PRIORITY specifies the priority for a StorPort miniport-created thread.

  StorThreadPriorityBackground,
  StorThreadPriorityNormal,
  StorThreadPriorityDelayed,
  StorThreadPriorityCritical,
  StorThreadPrioritySuperCritical,
  StorThreadPriorityHyperCritical,
  StorThreadPriorityRealTime
} STOR_THREAD_PRIORITY, *PSTOR_THREAD_PRIORITY;

Constants

 
StorThreadPriorityBackground

StorThreadPriorityDelayed
Indicates an ordinary worker thread. The assigned priority level is 12.

Remarks

A miniport sets thread priority when it calls StorPortCreateSystemThread to create a thread, and can change thread priority in StorPortSetPriorityThread.

Every thread has a scheduling priority (its thread priority). Higher values indicate higher priority threads.

See Thread Priorities for general information.
