EventConfig::setMaxDispatchInterval

Prevents priority inversion

&reftitle.description; public `void` `EventConfig::setMaxDispatchInterval` `int` `max_interval` `int` `max_callbacks` `int` `min_priority`

Prevents priority inversion by limiting how many low-priority event callbacks can be invoked before checking for more high-priority events.

Available since `libevent 2.1.0-alpha` .

&reftitle.parameters;

`max_interval`

- An interval after which Libevent should stop running callbacks and check for more events, or `0` , if there should be no such interval.

`max_callbacks`

- 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.

`min_priority`

- A priority below which `max_interval` and `max_callbacks` should 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 `1` and above, and so on.
