Return Codes:
| AUDIT_RET_SUCCESS |
| AUDIT_RET_FAILURE |

Comments:
cobaudit_event() is intended for use by C programs. It is used to return the next audit record from the file(s) associated with the current handle.
The function will return AUDIT_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 AUDIT_RET_FILE_NO_MORE_RECORDS.
