The name of a fullword in which the setgrent service returns 0.
The setgrent service is intended to be used to interrupt a sequential search of the group database from the calling task. The getgrent service performs the sequential search. When the setgrent service is called, it resets the search point for the current task in the group database to the beginning. The next getgrent service that is called from this task after this point starts searching the group database from the beginning.
There are no restrictions on the use of the setgrent service.
For an example using this callable service, see BPX1SGE (setgrent) example.
