CEvent::SetEvent 是 Windows 32 系统编程 API 中的一个函数，用于线程间通信。函数原型如下:BOOL SetEvent(HANDLE hEvent);其中，hEvent 参数表示事件句柄。返回值说明：如果操作成功，则返回非零值。如果操作失败，则返回 0。通过使用 SetEvent 函数，开发者可以向一个事件对象发送信号，从而通知等待...

CEvent g_event; 在程序中能够通过调用CEvent::SetEvent设置事件为有信号状态。 综合: 首先介绍CreateEvent是创建windows事件的意思,作用主要用在推断线程退出,程锁定方面. CreateEvent 函功能描写叙述:创建或打开一个命名的或无名的事件对象. EVENT有两种状态:发信号,不发信号。

用ResetEvent函数可以手工将事件对象置为无信号状态。 相反SetEvent函数将事件对象置为有信号状态。 PulseEvent函数将事件对象置为有信号状态,然后立即置为无信号状态,在实际开发中这个函数很少使用。
