CM_Get_DevNode_Status_Ex function
[Beginning with Windows 8 and Windows Server 2012, this function has been deprecated. Please use CM_Get_DevNode_Status instead.]
The CM_Get_DevNode_Status_Ex function obtains the status of a device instance from its device node (devnode) on a local or a remote machine's device tree.
Syntax

Parameters
- pulStatus [out]

Address of a location to receive status bit flags. The function can set any combination of the DN_-prefixed bit flags defined in Cfg.h.
- pulProblemNumber [out]
-
Address of a location to receive one of the CM_PROB_-prefixed problem values defined in Cfg.h. Used only if DN_HAS_PROBLEM is set in pulStatus.
- dnDevInst [in]

Caller-supplied device instance handle that is bound to the machine handle supplied by hMachine.

Note Using this function to access remote machines is not supported beginning with Windows 8 and Windows Server 2012, as this functionality has been removed.
Return value
If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.
Remarks
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.
