Deleting Swap Files
The file is not deleted until all the current processes using the file have
terminated and NSKCOM is started by a super-group user (255, n). When
NSKCOM is started by a super-group user (255, n), NSKCOM searches for
files that are marked for deletion and that are not in use and deletes them.
In Example 3-13 on page 3-14, the STOP and DELETE commands are not
completed immediately because the swap file is in use. The DELETE
command is not completed immediately, but the file is marked for deletion. The
user then exits NSKCOM. When a super-group user (255, n) later starts
NSKCOM again, NSKCOM searches for files to delete and deletes them.
For complete information on syntax for the STOP and DELETE commands, see
Section 4, NSKCOM Command Reference.
