-.Pp
-.Fn rc_strlist_add
-adds a malloced copy of
-.Fa item
-to
-.Fa list ,

-success, or NULL on failure and sets
-.Va errno
-accordingly.
-.Fn rc_strlist_addu
-and
-.Fn rc_strlist_addsortu
-only work if
-.Fa list
-does not already contain
-.Fa item .
-.Fn rc_strlist_addsort
-adds the item to the list in a lexically sorted position, using
-.Nm strcoll ,
-whereas
-.Fn rc_strlist_addsortc
-uses
-.Nm strcmp .
-.Pp
-.Fn rc_strlist_delete
-removes and frees
-.Fa item
-from
-.Fa list ,
-retuning true on success, otherwise false.
-.Pp
-.Fn rc_strlist_join
-appends
-.Fa list2
-to the end of
-.Fa list1
-and returns a pointer to the last item on the new list.
-.Pp
-.Fn rc_strlist_reverse
-reverses the items on
-.Fa list .
-.Pp
-.Fn rc_strlist_free
-frees each item on
-.Fa list
-and the
-.Fa list
-itself.
