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

CMAPI CONFIGRET CM_Get_DevNode_Status_Ex(
  PULONG   pulStatus,
  PULONG   pulProblemNumber,
  DEVINST  dnDevInst,
  ULONG    ulFlags,
  HMACHINE hMachine
);

Parameters

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.

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.

dnDevInst

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

ulFlags

Not used, must be zero.

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.
