If an implementation provides -- package Interfaces.C, this test must compile, execute, and -- report "PASSED". -- -- CHANGE HISTORY: -- 01 Sep 95 SAIC Initial prerelease version. -- 09 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. -- 26 Oct 96 SAIC Incorporated reviewer comments. -- 14 Sep 99 RLB Removed incorrect and unnecessary -- Unchecked_Conversion. -- --! with Report; with Interfaces.C; -- N/A => ERROR with Ada.Characters.Latin_1; with Ada.Characters.Handling; with Ada.Exceptions; with Ada.Strings.Wide_Fixed; procedure CXB3007 is begin Report.Test ("CXB3007", "Check that the procedures To_C and To_Ada " & "for wide strings produce correct results"); Test_Block: declare use Interfaces, Interfaces.C; use Ada.Characters, Ada.Characters.Handling; use Ada.Exceptions; use Ada.Strings.Wide_Fixed; TC_Short_Wide_String : Wide_String(1..4) := (others => Wide_Character'First); TC_Wide_String : Wide_String(1..8) := (others => Wide_Character'First); TC_wchar_array : wchar_array(0..7) := (others => wchar_t'First); TC_size_t_Count : size_t := size_t'First; TC_Natural_Count : Natural := Natural'First; -- We can use the wide character forms of To_Ada and To_C here to check -- the results; they were tested in CXB3006.
