Ev::nowUpdate

(PECL ev >= 0.2.0)

Ev::nowUpdateEstablishes the current time by querying the kernel, updating the time returned by Ev::now in the progress

说明

final public static Ev::nowUpdate(): void

Establishes the current time by querying the kernel, updating the time returned by Ev::now() in the progress. This is a costly operation and is usually done automatically within Ev::run() .

This method is rarely useful, but when some event callback runs for a very long time without entering the event loop, updating libev 's consideration of the current time is a good idea.

参数

此函数没有参数。

返回值

没有返回值。

  • Ev::now() - Returns the time when the last iteration of the default event loop has started
