If you need to suppress invocation when higher priority events are pending you need to look at ev_idle watchers, which provide this functionality.

You must not change the priority of a watcher as long as it is active or +pending.

The default priority used by watchers when no priority has been set is always 0, which is supposed to not be too high and not be too low :).

Setting a priority outside the range of EV_MINPRI to EV_MAXPRI is fine, as long as you do not mind that the priority value you query might or might not have been adjusted to be within valid range.

ev_invoke (loop, ev_TYPE *watcher, int revents)

Invoke the watcher with the given loop and revents. Neither +loop nor revents need to be valid as long as the watcher callback +can deal with that fact.

Also sets a callback, but uses a static method or plain function as callback. The optional data argument will be stored in the watcher's data member and is free for you to use.

The prototype of the function must be void (*)(ev::TYPE &w, int).

See the method-set above for more details.
