EvWatcher::clear — Clear watcher pending status


Описание

public int EvWatcher::clear ( void )

If the watcher is pending, this method clears its pending status and returns its revents bitset(as if its callback was invoked). If the watcher isn't pending it does nothing and returns 0 .

Sometimes it can be useful to "poll" a watcher instead of waiting for its callback to be invoked, which can be accomplished with this function.
