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.
