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. end Ada.Strings.Wide_Wide_Unbounded.Aux;
