_FEATURE_DATA_INCREMENTAL_STREAMING_WRITABLE structure

Description

The FEATURE_DATA_INCREMENTAL_STREAMING_WRITABLE structure contains information about the Incremental Streaming Writable feature.

Members

`Header`

Contains a FEATURE_HEADER structure with header information for this feature descriptor.

`DataTypeSupported`

Indicates the supported data type. See the SCSI Multimedia - 4 (MMC-4) specification for an explanation of the values that this member can take. DataTypeSupported[0] must hold the most significant byte of the number of the data type. DataTypeSupported[1] must hold the least significant byte of the number.

`BufferUnderrunFree`

Indicates, when set to one, that the logical unit is capable of zero-loss linking.

`AddressModeReservation`

`TrackRessourceInformation`

`Reserved01`

`NumberOfLinkSizes`

Specifies the number of link sizes available for the current media. See the MMC-3 specification for an explanation of the values that this member can take.

`LinkSize`

Contains an array that indicates the number of logical blocks per link.

Remarks

This structure holds data for the feature named "Incremental Streaming Writable" by the MMC-3 specification. Devices that support this feature can write data to a contiguous region, and can append data to a limited number of locations on the media. On CD media, this is known as "packet recording" and on a DVD media it is known as "incremental recording".
