CM_Get_DevNode_Status_Ex function

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
WINAPI CM_Get_DevNode_Status_Ex(
  _Out_     PULONG pulStatus,
  _Out_     PULONG pulProblemNumber,
  _In_      DEVINST dnDevInst ,
  _In_      ULONG ulFlags,
  _In_opt_  HMACHINE hMachine
);

Parameters

pulStatus [out]

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 [out]

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 [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.
