Available since libevent 2.1.0-alpha .
An interval after which Libevent should stop running callbacks and check for more events, or
0, if there should be no such interval.
A number of callbacks after which Libevent should stop running callbacks and check for more events, or
-1, if there should be no such limit.
A priority below which
max_callbacksshould not be enforced. If this is set to
0, they are enforced for events of every priority; if it's set to
1, they're enforced for events of priority
1and above, and so on.
