hIntEvent = OpenEvent(EVENT_ALL_ACCESS, FALSE, L"\\1394pcie\\MyEvent") 是一个打开事件对象的操作。根据提供的参数,它尝试以所有访问权限打开名为 "\\1394pcie\\MyEvent" 的事件对象。如果打开失败可能有以下几个因:
1. 事件对象不存在:请确保名为 "\\4pcie\\MyEvent" 的事件对象已经被创建。如果事件对象不存在,需要先使用 CreateEvent 函数创建该事件对象。
2. 权限不:如果当前用户没有足够的权限来打开事件对象,可能会导致打开失败。请确保当前用户具有足够的权限来打开该事件对象。
3. 名称错误:请检查事件对象的名称是否正确。确名称的大小写和特殊字符与创建事件对象时一致。
如果以上原因都排除了,但仍然无法打事件对象,请提供更多的上下文信息,以便我够更好地帮助你解决问题。
