NOTE: Data segment management (DS) intrinsics are not recommended for use in the native mode programming environment. Use of DS intrinsics in NM will degrade your program's performance. |
Syntax
U16V U16V
FREEDSEG (index, id);
Parameters
- index
16-bit unsigned integer by value (required)
Passes the index assigned to the data segment, obtained from a GETDSEG intrinsic call.
- id
16-bit unsigned integer by value (required)
Passes the identification assigned to the segment. Enter zero if none is assigned.
Operation Notes
If this is a private data segment or a shareable (nonprivate) segment not currently assigned to any other process in the job/session, the segment is deleted from the entire job/session. If it is a shareable segment that is currently assigned to another process, it is deleted from the calling process but continues to exist in the job/session. If the process is running in privileged mode when the extra data segment is acquired, then the process must be in privileged mode when it invokes FREEDSEG.
Condition Codes
- CCE (2)
Request granted. The data segment is deleted from the job/session.
- CCG (0)
Request granted. The data segment is deleted from the calling process but continues to exist in the job/session; it is being shared by another process.
- CCL (1)
Request denied. Either the index is invalid, or index and id do not specify the same shared data segment.
