EvIdle (class)

The EvIdle class

Introduction

(PECL ev >= 0.2.0)

EvIdle watchers trigger events when no other events of the same or higher priority are pending ( EvPrepare , EvCheck and other EvIdle watchers do not count as receiving events ).

Thus, as long as the process is busy handling sockets or timeouts(or even signals) of the same or higher priority it will not be triggered. But when the process is in idle(or only lower-priority watchers are pending), the EvIdle watchers are being called once per event loop iteration - until stopped, that is, or the process receives more events and becomes busy again with higher priority stuff. 登录查看完整内容
