The Retrieve Image Catalogs (QVOIRCLG) API retrieves the list of image catalog names based on the image catalog type parameter.
The receiver variable that receives the information requested. You can specify the size of the area to be smaller than the format requested as long as you specify the length parameter correctly. As a result, the API returns only the data that the area can hold.
The length of the receiver variable provided. The length of the receiver variable parameter may be specified up to the size of the receiver variable specified in the user program. If the length of the receiver variable parameter specified is larger than the allocated size of the receiver variable specified in the user program, the results are not predictable. The minimum length is 8 bytes.
The format of image catalogs to retrieve. You can use one of the following format names:
| RCLG0100 | Catalog list information. |
The type of image catalogs to include in the list. You can specify one of the following types:
| 0 | Specify this value to get all types of image catalogs. |
| 1 | Specify this value to get optical type image catalogs. |
| 2 | Specify this value to get tape type image catalogs. |
The structure in which to return error information. For the format of the structure, see Error code parameter.

Bytes available. The number of bytes of data available to be returned. All available data is returned if enough space is provided.
Bytes returned. The number of bytes of data returned.
Dependent image catalog indicator. An indicator of whether this image catalog is a dependent image catalog. The possible values are:
| 0 | This catalog is not a dependent catalog. |
| 1 | This catalog is a dependent catalog. |
Image catalog library name. The name of the library containing the image catalog.
Image catalog list. The list of image catalogs and information.
Image catalog mode. The current mode for a loaded optical image catalog. The possible values are:
| 0 | Not ready or tape type image catalog. |
| 1 | Normal. |
| 2 | Library. |
Image catalog name. The name of the image catalog from which the information was retrieved.
Image catalog status. The current status of the image catalog. The possible values are:
| 0 | Not ready. |
| 1 | Ready. |
| 2 | Unknown. |
Image catalog text. The text associated with this image catalog.
Image catalog type. The type of this image catalog. The possible values are:
| 0 | Optical type image catalog. |
| 1 | Tape type image catalog. |
Length of image catalog list entry. The length of each image catalog entry in the list.
Number of image catalogs. The number of image catalogs on the system of the type specified.
Number of image catalogs returned. The number of image catalogs returned.
Offset to first image catalog in list. The offset to the first image catalog in the list.
Reference image catalog indicator. An indicator of whether a dependent image catalog was created, with this catalog as the reference image catalog. The possible values are:
| 0 | This catalog is not a reference catalog. |
| 1 | This catalog is a reference catalog. |
Reference image catalog library name. The library containing the image catalog that was named as the reference catalog when this catalog was created. If this image catalog is not a dependent image catalog, this field will be blank.
Reference image catalog name. The image catalog named as the reference catalog when this catalog was created. If this image catalog is not a dependent image catalog, this field will be blank.
Reserved. Space included for alignment.
Virtual device name. The name of the virtual device associated with the image catalog. A blank virtual device name indicates that the catalog is not associated with a virtual device.
Virtual device status. The current status of the virtual device. The possible values are:
| 0 | Varied off. |
| 1 | Varied on. |
| 2 | Active. |
| 3 | No virtual device. |
