The IoWMIHandleToInstanceName routine determines the instance name for the WMI class instance implemented by the driver that is specified by a file handle.
DataBlockObject [in]Pointer to a WMI data block object. The caller opens the data block object for the WMI class with the IoWMIOpenBlock routine.
FileHandle [in]Specifies a file handle. The routine returns the instance name corresponding to the driver that is represented by the file handle.
InstanceName [out]Pointer to the UNICODE_STRING structure that the routine uses to return the instance name. The caller frees the returned buffer within UNICODE_STRING.
The routine returns an NTSTATUS code. Possible return values include:
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The operation succeeded. The routine fills the UNICODE_STRING structure pointed to by the InstanceName parameter with the instance name. |
| STATUS_WMI_INSTANCE_NOT_FOUND | The driver does not implement any instances of the WMI class specified by DataBlockObject. |
