The Pcntl\QosClass Enum

(PHP 8 >= 8.4.0)

简介

The Pcntl\QosClass enum is used to specify the user process priority with pcntl_setqos_class().

namespace Pcntl;

enum QosClass
{

case UserInteractive ; // Runs the process as the highest priority level.

case UserInitiated ; // Runs the process at high priority level but below UserInteractive ones.

case Default ; // Runs the process after all high-priority processes but before the low-priority ones.

case Utility ; //Pcntl\QosClass::Utility description

case Background ; // Runs the process after all high-priority ones had ran their courses.

}
