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

IOCTL_CHANGER_INITIALIZE_ELEMENT_STATUS IOCTL

Description

Initializes the status of all elements or of specified number of elements of a particular type.

Parameters

Major code

Input buffer

The buffer at Irp->AssociatedIrp.SystemBuffer contains an CHANGER_INITIALIZE_ELEMENT_STATUS structure that indicates the element type and the number of elements to initialize. If the BarCodeScan member is TRUE and CHANGER_BAR_CODE_SCANNER_INSTALLED is also set in Features0 of GET_CHANGER_PARAMETERS, the elements should be initialized using a bar code scan.

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_INITIALIZE_ELEMENT_STATUS).

Output buffer

None.

Output buffer length

None.

Input/output buffer

Input/output buffer length

Status block

The Information field is set to sizeof(CHANGER_INITIALIZE_ELEMENT_STATUS). The Status field is set to STATUS_SUCCESS, or possibly to STATUS_INFO_LENGTH_MISMATCH, STATUS_INSUFFICIENT_RESOURCES, STATUS_INVALID_ELEMENT_ADDRESS, or STATUS_INVALID_PARAMETER.

IOCTL_CHANGER_INITIALIZE_ELEMENT_STATUS IOCTL

Description

Initializes the status of all elements or the specified elements of a particular type.

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

BOOL DeviceIoControl(
  (HANDLE) hDevice,                         // handle to device
  IOCTL_CHANGER_INITIALIZE_ELEMENT_STATUS,  // dwIoControlCode
  (LPVOID) lpInBuffer,                      // input buffer
  (DWORD) nInBufferSize,                    // size of input buffer
  NULL,                                     // lpOutBuffer
  0,                                        // nOutBufferSize
  (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.
