CM_Get_Depth_Ex function
[Beginning with Windows 8 and Windows Server 2012, this function has been deprecated. Please use CM_Get_Depth instead.]
The CM_Get_Depth_Ex function is used to obtain the depth of a specified device node (devnode) within a local or a remote machine's device tree.
Syntax
CMAPI CONFIGRET WINAPI CM_Get_Depth_Ex( _Out_ PULONG pulDepth, _In_ DEVINST dnDevInst, _In_ ULONG ulFlags, _In_opt_ HMACHINE hMachine );
Parameters
- pulDepth [out]
-
Caller-supplied address of a location to receive a depth value, where zero represents the device tree's root node, one represents the root node's children, and so on.
- dnDevInst [in]
-
Caller-supplied device instance handle that is bound to the machine handle supplied by hMachine.
- ulFlags [in]
-
Not used, must be zero.
- hMachine [in, optional]
-
Caller-supplied machine handle to which the caller-supplied device instance handle is bound.
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.
