priority class

A priority class constant signifying above normal priority.

Refers to the base priority of the process, which determines the order in which threads are scheduled for the processor. The base priority is set by the process code (not the OS), however the OS sets and changes the dynamic priorities of threads in the process within the range of the base. Use the Task Manager to change the base priority of processes.

Returns a priority class object with 'below normal' priority. This applies to threads that can wait for other threads to complete before running. Threads with this status are in between idle and normal priority.

Returns a priority class object with 'high' priority. These threads will steal processor time from other threads and should be used very carefully. Typically, they are used strictly for responding to time-critical events.

Returns a priority class object with 'idle' priority. Processes that monitor the Client, such as screen savers, typically use this priority to keep them from interrupting higher priority threads.

Returns a priority class object with 'normal' priority. This is the default priority class of a process.

Returns a priority class object with 'realtime' priority. These threads should be sparingly used, since they may interrupt user input and some disk operations. They are typically used for short, time-sensitive communication with low level hardware.

Returns True if the two priority classes are the same.
