CM_Get_DevNode_Status function (cfgmgr32.h)
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.
