The CM_Get_DevNode_Status function obtains the status of a device instance from its device node (devnode) in the local machine's device tree.

Note

In Windows Vista, and later, the unified device property model uses the DEVPKEY_Device_DevNodeStatus property key to represent the device instance identifier. For details, see Retrieving the status and problem code for a device instance.

Syntax

CMAPI CONFIGRET CM_Get_DevNode_Status(
  [out] PULONG  pulStatus,
  [out] PULONG  pulProblemNumber,
  [in]  DEVINST dnDevInst,
  [in]  ULONG   ulFlags
);

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 local machine.

[in] ulFlags

Not used, must be zero.

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 the local machine, see CM_Get_Child.
