The ADSJobPriority enumeration encapsulates the execution priorities for jobs.

Value |
Description |
|
ADS_PRIORITY_NORMAL |
32 |
Indicates a normal process with no special scheduling needs. |
|
ADS_PRIORITY_IDLE |
64 |
Indicates a process whose threads run only when the system is idle and are preempted by the threads of any process running in a higher priority class. |
|
ADS_PRIORITY_HIGH |
128 |
Indicates a process that performs time-critical tasks. The threads of a high-priority class process preempt the threads of normal-priority or idle-priority class processes. An example is the Task List, which must respond quickly when called by the user, regardless of the load on the system. Use extreme care when using the high-priority class, because a CPU-bound application with a high-priority class can use nearly all available cycles. |
|
ADS_PRIORITY_REALTIME |
256 |
Indicates a process that has the highest possible priority. The threads of a real-time priority class process preempt the threads of all other processes, including operating system processes performing important tasks. For example, a real-time process that executes for more than a very brief interval can cause disk caches not to flush or cause the mouse to be unresponsive. |
