+-- This child package of Ada.Strings.Wide_Wide_Unbounded provides some
+-- specialized access functions which are intended to allow more efficient
+-- use of the facilities of Ada.Strings.Wide_Wide_Unbounded, particularly by
+-- other layered utilities.

+
+ procedure Get_Wide_Wide_String
+ (U : Unbounded_Wide_Wide_String;
+ S : out Wide_Wide_String_Access;
+ L : out Natural);
+ pragma Inline (Get_Wide_Wide_String);
+ -- This procedure returns the internal string pointer used in the
+ -- representation of an unbounded string as well as the actual current
+ -- length (which may be less than S.all'Length because in general there
+ -- can be extra space assigned). The characters of this string may be
+ -- not be modified via the returned pointer, and are valid only as
+ -- long as the original unbounded string is not accessed or modified.
+ --
+ -- This procedure is more efficient than the use of To_Wide_Wide_String
+ -- since it avoids the need to copy the string. The lower bound of the
+ -- referenced string returned by this call is always one, so the actual
+ -- string data is always accessible as S (1 .. L).
+
+ procedure Set_Wide_Wide_String
+ (UP : in out Unbounded_Wide_Wide_String;
+ S : Wide_Wide_String);
+ pragma Inline (Set_Wide_Wide_String);
+ -- This function sets the string contents of the referenced unbounded
+ -- string to the given string value. It is significantly more efficient
+ -- than the use of To_Unbounded_Wide_Wide_String with an assignment, since
+ -- it avoids the necessity of messing with finalization chains. The lower
+ -- bound of the string S is not required to be one.
+
+ procedure Set_Wide_Wide_String
+ (UP : in out Unbounded_Wide_Wide_String;
+ S : Wide_Wide_String_Access);
+ pragma Inline (Set_Wide_Wide_String);
+ -- This version of Set_Wide_Wide_String takes a string access value, rather
+ -- than string. The lower bound of the string value is required to be one,
+ -- and this requirement is not checked.
