EvWatcher::clearClear watcher pending status

説明

public EvWatcher::clear(): int

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.
