SetThreadPriority Function

Adjusts the priority of a thread relative to other processes.

Pascal

procedure SetThreadPriority(
    AThread: TIdNativeThread; 
    const APriority: TIdThreadPriority; 
    const APolicy: Integer = -MaxInt
);

Parameters

Parameters	Description
AThread	Thread for the priority assignment.
APriority	Priority value to assign for the specified thread.
APolicy	Default value is -1*MaxInt.

Description

SetThreadPriority is a Procedure used to adjust the priority of THE specified thread relative to other processes executing on the local computer system. SetThreadPriority calls the platform- or operating system-specific APIs required to adjust the thread priority.

Notes

Boosting the thread priority of a CPU intensive operation may adversely affect other threads in the application. Only apply priority boosts to threads that spend most of their time waiting for external events.

SetThreadPriority is used internally in Indy when a new thread scheduler is created.
