Windows Driver Kit DDI reference (ni-ntddchgr-ioctl_changer_query_volume_tags)

IOCTL_CHANGER_QUERY_VOLUME_TAGS IOCTL

Description

Returns volume tag information for the specified elements.

Parameters

Major code

Input buffer

The buffer at Irp->AssociatedIrp.SystemBuffer indicates the starting element for which to return information, the action to perform, and a template to use when searching for volume IDs.

Input buffer length

Parameters.DeviceIoControl.InputBufferLength in the I/O stack location indicates the size, in bytes, of the parameter buffer, which must be >= sizeof(CHANGER_SEND_VOLUME_TAG_INFORMATION).

Output buffer

The driver returns the READ_ELEMENT_ADDRESS_INFO data in the buffer at Irp->AssociatedIrp.SystemBuffer.

Output buffer length

Parameters.DeviceIoControl.OutputBufferLength indicates the size, in bytes, of the parameter buffer for output, which must be >= sizeof(READ_ELEMENT_ADDRESS_INFO).

Input/output buffer

Input/output buffer length

Status block

The Information field is set to the correct output buffer size, in bytes. The Status field is set to STATUS_SUCCESS, or possibly to STATUS_INFO_LENGTH_MISMATCH, STATUS_INSUFFICIENT_RESOURCES, STATUS_INVALID_DEVICE_REQUEST, or STATUS_INVALID_ELEMENT_ADDRESS.

IOCTL_CHANGER_QUERY_VOLUME_TAGS IOCTL

Description

Retrieves the volume tag information for the specified elements.

To perform this operation, call the DeviceIoControl function with the following parameters.

BOOL DeviceIoControl(
  (HANDLE) hDevice,                 // handle to device
  IOCTL_CHANGER_QUERY_VOLUME_TAGS,  // dwIoControlCode
  (LPVOID) lpInBuffer,              // input buffer
  (DWORD) nInBufferSize,            // size of input buffer
  (LPVOID) lpOutBuffer,             // output buffer
  (DWORD) nOutBufferSize,           // size of output buffer
  (LPDWORD) lpBytesReturned,        // number of bytes returned
  (LPOVERLAPPED) lpOverlapped       // OVERLAPPED structure
);

Parameters

Input buffer

Input buffer length

Output buffer

Output buffer length

Input/output buffer

Input/output buffer length

Status block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful.

Otherwise, Status to the appropriate error condition as a NTSTATUS code.

For more information, see NTSTATUS Values.
