The Retrieve User Space Attributes (QUSRUSAT) API retrieves information about the current attributes and the current operational statistics of the user space.
You can also retrieve information about user space attributes by using one of the following:
The variable that is to receive the information requested. You can specify the size of this 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. If the length is larger than the size of the receiver variable, the results may not be predictable. The minimum length is 8 bytes.
The format of the space information to be returned.
The format names supported are:
| SPCA0100 | Basic information |
Refer to SPCA0100 Format for details on the format.
The user space for which you want to retrieve information, 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 library list |
The structure in which to return error information. For the format of the structure, see Error Code Parameter.
The following information about a user space is returned for the SPCA0100 format. For detailed descriptions of the fields in the table, see Field Descriptions.
| Offset | Type | Field | |
|---|---|---|---|
| Dec | Hex | ||
| 0 | 0 | BINARY(4) | Bytes returned |
| 4 | 4 | BINARY(4) | Bytes available |
| 8 | 8 | BINARY(4) | Space size |
| 12 | C | CHAR(1) | Automatic extendibility |
| 13 | D | CHAR(1) | Initial value |
| 14 | E | CHAR(10) | User space library name |
Automatic extendibility. Whether or not the space is extended automatically by the system when the end of the space is encountered.
| 0 | Space is not automatically extendible |
| 1 | Space is automatically extendible |
Bytes available. The length of all data available to return. All available data is returned if enough space is provided.
Bytes returned. The length of the data actually returned.
Initial value. The initial value to which future extensions of the user space will be set.
Space size. The size of the user space object in bytes.
User space library name. The library in which the user space is located. This is helpful when *LIBL or *CURLIB is specified as the library name in the qualified user space name parameter.
