45 ;;; Check an OCI return code for erroricity and signal a reasonably
46 ;;; informative condition if so.
48 ;;; ERRHP provides an error handle which can be used to find
49 ;;; subconditions; if it's not provided, subcodes won't be checked.
51 ;;; NULLS-OK says that a NULL-VALUE-RETURNED subcondition condition is
52 ;;; normal and needn't cause any signal. An error handle is required
53 ;;; to detect this subcondition, so it doesn't make sense to set ERRHP
54 ;;; unless NULLS-OK is set.
