SetPriorityClass - a function that sets the priority class for a specified process. This function is specific to Windows.
<delphi> The SetPriorityClass may have one of the following priority classes:
HIGH_PRIORITY_CLASS = High performs tasks immediately. IDLE_PRIORITY_CLASS = Idle performs tasks when the system is idle. NORMAL_PRIORITY_CLASS = Normal performs tasks at regular speed. REALTIME_PRIORITY_CLASS = Real Time performs tasks immediately and above all other tasks, including operating system tasks.
Use caution when using REALTIME_PRIORITY_CLASS. It can potentially take so much of the CPU resources that there may not be anything left for other items to run, including operating system requests. </delphi>
EXAMPLE:
<delphi> uses Windows; // Unit containing the SetPriorityClass function.
procedure TForm1.FormCreate(Sender: TObject); begin
SetPriorityClass(GetCurrentProcess(), HIGH_PRIORITY_CLASS);
// Sets the current running application to High Priority.
end;
</delphi>
