Use this interface to write a data stream to a device.
This interface should be used by those developing support for new media types or formats. Writing to media typically includes the following steps:
- Preparing the hardware by setting mode pages for the media.
- Querying the hardware to verify that the media is large enough.
- Initializing the write, for example, by formatting the media or setting OPC.
- Performing the actual WRITE commands.
- Finishing the write by stopping the formatting or closing the session or track.
Most client applications should use the IDiscFormat2Data interface to write images to a device.
To create an instance of this interface, call the CoCreateInstance function. Use__uuidof(MsftWriteEngine2) for the class identifier and __uuidof(IWriteEngine2) for the interface identifier.
The IWriteEngine2 interface inherits from the IDispatch interface. IWriteEngine2 also has these types of members:
The IWriteEngine2 interface has these methods.
| IWriteEngine2::CancelWrite Cancels a write operation that is in progress. |
| IWriteEngine2::get_BytesPerSector Retrieves the number of bytes to use for each sector during writing. The returned value indicates what the value previously set with IWriteEngine2::put_BytesPerSector, and does not return a current bytes per sector value for media. |
| IWriteEngine2::get_EndingSectorsPerSecond Retrieves the estimated number of sectors per second that the recording device can write to the media at the end of the writing process. |
| IWriteEngine2::get_Recorder Retrieves the recording device to use in the write operation. |
| IWriteEngine2::get_StartingSectorsPerSecond Retrieves the estimated number of sectors per second that the recording device can write to the media at the start of the writing process. |
| IWriteEngine2::get_UseStreamingWrite12 Retrieves a value that indicates if the write operations use the WRITE12 or WRITE10 command. |
| IWriteEngine2::get_WriteInProgress Retrieves a value that indicates whether the recorder is currently writing data to the disc. |
| IWriteEngine2::put_BytesPerSector Sets the number of bytes to use for each sector during writing. |
| IWriteEngine2::put_EndingSectorsPerSecond Sets the estimated number of sectors per second that the recording device can write to the media at the end of the writing process. |
| IWriteEngine2::put_Recorder Sets a recording device for the write operation. |
| IWriteEngine2::put_StartingSectorsPerSecond Sets the estimated number of sectors per second that the recording device can write to the media at the start of the writing process. |
| IWriteEngine2::put_UseStreamingWrite12 Sets a value that indicates if the write operations use the WRITE12 or WRITE10 command. |
| IWriteEngine2::WriteSection Writes a data stream to the current recorder. |
To create the MsftWriteEngine2 object in a script, use IMAPI2.MsftWriteEngine2 as the program identifier when calling CreateObject.
It is possible for a power state transition to take place during a burn operation (i.e. user log-off or system suspend) which leads to the interruption of the burn process and possible data loss. For programming considerations, see Preventing Logoff or Suspend During a Burn.
