CM_Locate_DevNode_ExA function (cfgmgr32.h)
[Beginning with Windows 8 and Windows Server 2012, this function has been deprecated. Please use CM_Locate_DevNode instead.]
The CM_Locate_DevNode_Ex function obtains a device instance handle to the device node that is associated with a specified device instance ID, on a local machine or a remote machine.
CMAPI CONFIGRET CM_Locate_DevNode_ExA( PDEVINST pdnDevInst, DEVINSTID_A pDeviceID, ULONG ulFlags, HMACHINE hMachine );
A variable of ULONG type that supplies one of the following flag values that apply if the caller supplies a device instance identifier:
The function retrieves the device instance handle for the specified device only if the device is currently configured in the device tree.
The function retrieves a device instance handle for the specified device if the device is currently configured in the device tree or the device is a nonpresent device that is not currently configured in the device tree.
The function retrieves a device instance handle for the specified device if the device is currently configured in the device tree or in the process of being removed for the device tree. If the device is in the process of being removed, the function cancels the removal of the device.
A machine handle obtained from a call to CM_Connect_Machine, or a machine handle to which a device information set is bound. The machine handle for a device information set is obtained from the RemoteMachineHandle member of the SP_DEVINFO_LIST_DETAIL_DATA structure for the device information set. Call SetupDiGetDeviceInfoListDetail to obtain an SP_DEVINFO_LIST_DETAIL_DATA structure.
If the operation succeeds, CM_Locate_DevNode returns CR_SUCCESS. Otherwise, the function returns one of the CR_-prefixed error codes that are defined in Cfgmgr32.h.
For information about using device instance handles that are bound to a local or a remote machine, see CM_Get_Child_Ex.
Functionality to access remote machines has been removed in Windows 8 and Windows Server 2012 and later operating systems thus you cannot access remote machines when running on these versions of Windows.
