CM_Get_DevNode_Status_Ex function (cfgmgr32.h)

[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

CMAPI CONFIGRET CM_Get_DevNode_Status_Ex(
  [out]          PULONG   pulStatus,
  [out]          PULONG   pulProblemNumber,
  [in]           DEVINST  dnDevInst,
  [in]           ULONG    ulFlags,
  [in, optional] HMACHINE hMachine
);

Parameters

[out] pulStatus

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.

[out] pulProblemNumber

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.

[in] dnDevInst

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

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.
