Element Type Code – This field specifies the element types selected for the returned information, as shown
in the following table.
Starting Element Address – This field specifies the minimum element address to report. Only elements
with an element type code specified by the Element Type Code field, and with an address greater than or
equal to the starting element address will be reported. The starting element address must be a valid element
address, but not have to be within the range specified by the Element Type Code field.
Number of Elements – This field specifies the maximum number of element descriptors to return. Only
those descriptors that can be completely transferred within the allotted allocation length will be returned.
Current Data (CurData) – This field specifies whether the library may cause device motion to confirm
element status data. The library will not cause device motion if this field is set to either 0 or 1.
Device ID (DVCID) – This field indicates whether device identifiers (inquiry page information or serial
numbers) are returned for the specified range. Identifiers are returned if this field is set to 1. They are not
returned if this field is set to 0. Only data transfer elements can return device identifiers.
Allocation Length – This field specifies the byte length allowed for returned element descriptors. Only
complete element descriptors are returned. The library returns element descriptors until one of the following
conditions are met:
• All available element descriptors have been returned
• The number of element descriptors specified in the Number of Elements field have been returned
• The number of bytes specified in the Allocation Length field have been returned
• There is less allocation length space available than is required by the next complete element
descriptor
