说明

public SyncEvent::__construct(string $name = ?, bool $manual = false, bool $prefire = false)

Constructs a named or unnamed event object.

参数

name: The name of the event if this is a named event object.

If the name already exists, it must be able to be opened by the current user that the process is running as or an exception will be thrown with a meaningless error message.

Only has impact if the calling process/thread is the first to create the object.

返回值

The new SyncEvent object.

错误／异常
