The List Subsystem Entries (QWDLSBSE) API lists some of the different entries in a subsystem description. See the format information for the types of entries available. QWDLSBSE replaces any data that already exists in the user space.
Other subsystem information is available through the following APIs:
The user space that receives the list, and the library in which it is located. The first 10 characters contain the user space name, and the second 10 characters contain the library name. You can use these special values for the library name:
| *CURLIB | The job's current library |
| *LIBL | The job's library list |
The format of subsystem entries to list. You can use one of the following format names:
| SBSE0100 | Routing entry list. For details, see SBSE0100 Format. |
| SBSE0200 | Communications entry list. For details, see SBSE0200 Format. |
| SBSE0300 | Remote locations entry list. For details, see SBSE0300 Format. |
| SBSE0400 | Autostart job entry list. For details, see SBSE0400 Format. |
| SBSE0500 | Prestart job entry list. For details, see SBSE0500 Format. |
| SBSE0600 | Workstation name entry list. For details, see SBSE0600 Format. |
| SBSE0700 | Workstation type entry list. For details, see SBSE0700 Format. |
The subsystem description about which to retrieve information, and the library in which the subsystem description is located. The first 10 characters contain the subsystem description name, and the second 10 characters contain the library name. You can use these special values for the library name:
| *CURLIB | The job's current library |
| *LIBL | The job's library list |
The structure in which to return error information. For the format of the structure, see Error code parameter.
The list of entries that the QWDLSBSE API returns into the user space consists of:
The user area and generic header are described in User spaces. The remaining items are described in the following sections. For detailed descriptions of the fields in the tables, see Field Descriptions.
When you retrieve list entry information from a user space, you must use the entry size returned in the generic header. The size of each entry may be padded at the end. If you do not use the entry size, the result may not be valid. For examples of how to process lists, see Examples: APIs and exit programs.
