GETVERSIONINPARAMS structure

Description

The GETVERSIONINPARAMS structure is used in conjunction with the SMART_GET_VERSION request to retrieve version information, a capabilities mask, and a bitmask for the indicated device.

Members

`bVersion`

Contains an integer that indicates the version number of the binary driver.

`bRevision`

Contains an integer that indicates the revision number of the binary driver.

`bReserved`

Reserved.

`bIDEDeviceMap`

Contains the bitmap. The following table explains the meaning of the bitmap:

Bitmap Flags	Meaning
Bit 0 is set to 1.	The device is either a SATA drive or an IDE drive. If it is an IDE drive, it is the master device on the primary channel.
Bit 1 is set to 1.	The device is an IDE drive, and it is the subordinate device on the primary channel.
Bit 2 is set to 1.	The device is an IDE drive, and it is the master device on the secondary channel.
Bit 3 is set to 1.	The device is an IDE drive, and it is the subordinate device on the secondary channel.
Bit 4 is set to 1.	The device is an ATAPI drive, and it is the master device on the primary channel.
Bit 5 is set to 1.	The device is an ATAPI drive, and it is the subordinate device on the primary channel.
Bit 6 is set to 1.	The device is an ATAPI drive, and it is the master device on the secondary channel.
Bit 7 is set to 1.	The device is an ATAPI drive, and it is the subordinate device on the secondary channel.

`fCapabilities`

Contains the bitmask of driver capabilities.

Bitmap Flags	Meaning
CAP_ATA_ID_CMD	The device supports the ATA ID command.
CAP_ATAPI_ID_CMD	The device supports the ATAPI ID command.
CAP_SMART_CMD	The device supports SMART commands.

`dwReserved`

Reserved.

Remarks

The SMART_GET_VERSION control code returns version information, a capabilities mask, and a bitmask for the device. This IOCTL must be handled by drivers that support Self-Monitoring Analysis and Reporting Technology (SMART).

Input Parameters

Parameters.DeviceIoControl.OutputBufferLength indicates the size, in bytes, of the buffer, which must be >= sizeof(GETVERSIONINPARAMS).
Output Parameters

The driver returns the information to the buffer at Irp->AssociatedIrp.SystemBuffer.
I/O Status Block

The driver sets the Information field to sizeof(GETVERSIONINPARAMS) when it sets the Status field to STATUS_SUCCESS. Otherwise, the driver sets the Information field to zero and sets the Status field to possibly STATUS_INVALID_PARAMETER.
