STORAGE_PROTOCOL_SPECIFIC_DATA_EXT structure

Description

The STORAGE_PROTOCOL_SPECIFIC_DATA_EXT structure describes the protocol-specific device data for IOCTL_STORAGE_QUERY_PROPERTY and IOCTL_STORAGE_SET_PROPERTY requests.

Members

`ProtocolType`

The protocol type. Values for this member are defined in the STORAGE_PROTOCOL_TYPE enumeration.

`DataType`

The protocol data type. Data types are defined in the STORAGE_PROTOCOL_NVME_DATA_TYPE and STORAGE_PROTOCOL_ATA_DATA_TYPE enumerations.

`ProtocolDataValue`

The protocol data value.

`ProtocolDataSubValue`

Sub-value of the protocol data value.

`ProtocolDataOffset`

The offset of the data buffer from the beginning of this structure. The typical value is sizeof(STORAGE_PROTOCOL_SPECIFIC_DATA_EXT).

`ProtocolDataLength`

The length of the protocol data. ProtocolDataLength must be >= 512 bytes.

`FixedProtocolReturnData`

The returned data.

`ProtocolDataSubValue2`

First additional data sub-value.

`ProtocolDataSubValue3`

Second additional data sub-value.

`ProtocolDataSubValue4`

Third additional data sub-value.

`ProtocolDataSubValue5`

Fourth additional data sub-value.

`ProtocolDataSubValue6`

Fifth additional data sub-value.

`Reserved[4]`

Reserved for future use; do not use.
