Pointer to array of pointer items. Each array element addresses an audit data item of the type and length indicated by the corresponding element in the cblte-audrec-event-type and cblte-audrec-event-len arrays respectively. Will be NULL if cblte-audrec-data-count is 0.

Return Codes:

78-AUD-RET-SUCCESS
78-AUD-RET-FAILURE
78-AUD-RET-NOT-ENOUGH-MEMORY

Comments:

CBL_AUDIT_FILE_READ() is used to return the next audit record from the file(s) associated with the current handle.

The function will return 78-AUD-RET-FILE-EOF when attempting to read past the last record in a file for the first time. The next attempt to read past the last record will either return the first record of the next file in the collection if a collection has been opened and another file is available, or 78-AUD-RET-FILE-NO-MORE-RECORDS.

Examples:

copy "mfaudit.cpy ".

01 auditfile-handle  pic x(4) comp-5.
01 auditfile-record  cblt-aud-record.
01 flags             pic x(4) comp-5.
...
compute flags = 0
