Ev::run — Begin checking for events and calling callbacks for the default loop
Begin checking for events and calling callbacks for the default loop. Returns when a callback calls Ev::stop() method, or the flags are nonzero(in which case the return value is true) or when there are no active watchers which reference the loop( EvWatcher::keepalive() is true), in which case the return value will be false. The return value can generally be interpreted as if true, there is more work left to do.
flagsOptional parameter flags can be one of the following:
flags | Description |
|---|---|
0 | The default behavior described above |
Ev::RUN_ONCE | Block at most one(wait, but don't loop) |
Ev::RUN_NOWAIT | Don't block at all(fetch/handle events, but don't wait) |
No value is returned.
