Ev::nowUpdate — Establishes 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 ) : 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.
