所有驅動程式都必須準備好在DispatchPnP常式中服務IRP_MJ_PNP要求。傳送時PnP 管理員會在列舉、資源重新平衡期間傳送IRP_MJ_PNP要求,以及系統上發生任何其他時間隨插即用活動。 驅動程式也可以根據次要函式程式碼,傳送特定 IRP_MJ_PNP 要求。輸入參數取決於 IRP 目前 I/O 堆疊位置中 MinorFunction 的值。 每個 ...
The Plug and Play Manager sends the IRP_MJ_PNP request whenever Plug and Play activity occurs on the system. Other operating system components and other kernel-mode drivers can also send certain IRP_MJ_PNP requests, depending on the minor function code. ...

Display drivers are among these: if I ask the PnP manager to “safely remove VTBook”, it answers that “The device cannot be stopped right now. Try later”. It’s because, I guess, there is no driver that handles the IRP_MJ_PNP IRPs. ...
IRP MJ PNP类似于Win32编程中的Windows消息 而IRP MJ PNP的派遣函数则 像Win32编程中的窗口函数。 1列出了即插即用IRP的二十多个副功能码。其中有九个副功能码仅能由总线驱动程序处理 以星号标出 本驱动中实现了派遣函数的副功能码以对号标出 其余未实现派遣函数的副功能码的IRP 本驱动只需要把它们向底层驱动...
所有驱动程序都必须准备好为 DispatchPnP 例程中的IRP_MJ_PNP请求提供服务。发送时PnP 管理器在枚举、资源重新均衡以及系统上发生即插即用活动的任何其他时间发送IRP_MJ_PNP请求。 驱动程序还可以发送某些 IRP_MJ_PNP 请求,具体取决于次要函数代码。输入参数取决于 IRP 当前 I/O 堆栈位置中 MinorFunction 处的值。
取決於 IRP 目前 I/O 堆疊位置中MinorFunction的值。 作業 如需IRP_MJ_PNP要求的詳細資訊,請參閱隨插即用次要 IRP。 規格需求 標頭 Wdm.h (包括 Wdm.h、Ntddk.h 或 Ntifs.h) 另請參閱 DispatchPnP 意見反映 此頁面有幫助嗎? 是否 提供產品意見反映| ...
