EventConfig::setMaxDispatchInterval

(PECL event >= 2.1.0-alpha)

EventConfig::setMaxDispatchInterval — Prevents priority inversion

Descrizione

public EventConfig::setMaxDispatchInterval( int $max_interval , int $max_callbacks , int $min_priority ): void

Prevents 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.

Elenco dei parametri

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.

Valori restituiti

Restituisce true in caso di successo, false in caso di fallimento.
