For most of the above macros, declaring a type as part of the access flags is
not necessary -- however, when declaring a sysctl implemented by a function,
including a type in the access mask is required:
-.Bl -tag -width CTLTYPE_STRING
+.Bl -tag -width ".Dv CTLTYPE_STRING"
.It Dv CTLTYPE_NODE
This is a node intended to be a parent for other nodes.
.It Dv CTLTYPE_INT
.Pp
All sysctl types except for new node declarations require one or more flags
to be set indicating the read and write disposition of the sysctl:
-.Bl -tag -width CTLFLAG_ANYBODY
+.Bl -tag -width ".Dv CTLFLAG_ANYBODY"
.It Dv CTLFLAG_RD
This is a read-only sysctl.
.It Dv CTLFLAG_WR

If the first step of context deletion fails,
re-registration of the oid does not change the already assigned oid number
-(which is different from OID_AUTO).
+(which is different from
+.Dv OID_AUTO ) .
This ensures that re-registered entries
maintain their original positions in the tree.
