_CHANGER_PRODUCT_DATA structure

Description

The CHANGER_PRODUCT_DATA structure is used in conjunction with the IOCTL_CHANGER_GET_PRODUCT_DATA request to retrieve product data for a device.

Members

VendorId

Specifies the name of the device manufacturer.

ProductId

Specifies the product identification as defined by the vendor.

Revision

Specifies the product revision as defined by the vendor.

SerialNumber

Specifies the value defined by the vendor to identify this device. Serial numbers are unique for all changers of a given type, but are not necessarily unique across vendor and product lines. For a SCSI changer, this value might be from Vital Product Data. If SerialNumber is not unique, the miniclass driver should not set the CHANGER_SERIAL_NUMBER_VALID flag in the Features0 member of the GET_CHANGER_PARAMETERS structure.

DeviceType

Specifies the device type of the changer. This member must be MEDIUM_CHANGER.
