The Retrieve Image Catalog Details (QVOIRCLD) API retrieves the contents of an image catalog. The QVOIRCLD API places the information in the receiver variable.
The receiver variable that is to receive the catalog information. 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 catalog entries to list. You can use one of the following format names:
| RCLD0100 | Header information only. |
| RCLD0200 | Header information and entry list for optical image catalogs. |
| RCLD0300 | Header information and entry list for tape image catalogs. |
The image catalog about which to list information, and the library in which it is located. The first 10 characters contain the object name, and the second 10 characters contain the library name.
The structure in which to return error information. For the format of the structure, see Error code parameter.
