PHP 8.4.2 Released!

    The SyncEvent class

    (PECL sync >= 1.0.0)

    简介

    A cross-platform, native implementation of named and unnamed event objects. Both automatic and manual event objects are supported.

    An event object waits, without polling, for the object to be fired/set. One instance waits on the event object while another instance fires/sets the event. Event objects are useful wherever a long-running process would otherwise poll a resource (e.g. checking to see if uploaded data needs to be processed).

    类摘要

    class SyncEvent {
    /* 方法 */
    public __construct(string $name = ?, bool $manual = false, bool $prefire = false)
    public fire(): bool
    public reset(): bool
    public wait(int $wait = -1): bool
    }
