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