EvWatcher::clear — Clear watcher pending status
설명
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.
