PROCESS GET PRIORITY retrieves the priority value
for the current process. The
retrieved priority value is assigned to the long
or dword variable designated by lResult&.
The process priority value is one of the following:
%IDLE_PRIORITY_CLASS =
&H00000040
|
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. An example is a screen saver. The
idle priority class is inherited by child processes. |
%NORMAL_PRIORITY_CLASS =
&H00000020
|
Indicates a normal process
with no special scheduling needs. |
%HIGH_PRIORITY_CLASS =
&H00000080
|
Indicates a process that
performs time-critical tasks that must be
executed immediately for it to run correctly. The threads of a high-priority
class process preempt the threads of normal or idle priority class processes.
An example is Windows Task List, which must respond quickly when called
by the user, regardless of the load on the operating system. Use extreme
care when using the high-priority class, because a high-priority class
CPU-bound application can use nearly all available cycles. |
%REALTIME_PRIORITY_CLASS = &H00000100
|
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. |
