EventConfig::setMaxDispatchInterval — Prevents priority inversion
$max_interval, int$max_callbacks, int$min_priority): voidPrevents priority inversion by limiting how many low-priority event callbacks can be invoked before checking for more high-priority events.
Nota:
Available since
libevent 2.1.0-alpha.
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.
