[Beginning with Windows 8 and Windows Server 2012, this function has been deprecated. Please use CM_Get_Parent instead.]

The CM_Get_Parent_Ex function obtains a device instance handle to the parent node of a specified device node (devnode) in a local or a remote machine's device tree.

Syntax

CMAPI CONFIGRET CM_Get_Parent_Ex(
  [out]          PDEVINST pdnDevInst,
  [in]           DEVINST  dnDevInst,
  [in]           ULONG    ulFlags,
  [in, optional] HMACHINE hMachine
);

Parameters

[out] pdnDevInst

Caller-supplied pointer to the device instance handle to the parent node that this function retrieves. The retrieved handle is bound to the machine handle specified by hMachine.

[in] dnDevInst

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

[in] ulFlags

Not used, must be zero.

[in, optional] hMachine

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.
