参数
Flags
[in] 标志的组合。 PROVIDER_FLAGS 枚举的。 下面的标志。这是典型的调用:Flag
说明
PFLAG_REMOTE_PORT
调用方在远程计算机上运行。
PFLAG_DEBUGGEE
调用方当前正在调试 (有关排列的附加信息对每个节点返回)。
PFLAG_ATTACHED_TO_DEBUGGEE
调用方附加到，但未由调试器启动。
PFLAG_REASON_WATCH
调用方想要观看事件。 如果此未设置任何标志。 然后移除回调事件，并调用方不再接收通知。
pPort
[in] 调用过程的端口运行。processId
[in] 保存包含相关的程序进程的 ID 的 AD_PROCESS_ID 结构。EngineFilter
[in] 数组 GUID 调试引擎与处理。guidLaunchingEngine
[in] 生成此调试引擎的 GUID 处理 (如果有)。pEventCallback
[in] 接收事件通知的 IDebugPortNotify2 对象。
返回值
如果成功，则返回; S_OK否则，返回错误代码。
备注
当调用方若要移除建立与以前的事件处理程序时调用此方法，调用方通过与首次的参数，后者意味着 PFLAG_REASON_WATCH 标志。
