ElementList
A CHANGER_ELEMENT_LIST structure that contains an array of structures that represents the range of elements for which information is to be retrieved. The ElementType member of each structure can be one of the following values: ChangerDrive, ChangerSlot, ChangerTransport, ChangerIEPort, or AllElements.
VolumeTagInfo
If this member is TRUE, volume tag information is to be retrieved. Otherwise, no volume information is retrieved. A volume tag can be a bar code or an application-defined value. This member is valid only if the Features0 member of the GET_CHANGER_PARAMETERS structure is CHANGER_BAR_CODE_SCANNER_INSTALLED or CHANGER_VOLUME_IDENTIFICATION.
