--
-- OBJECTIVE:
-- Check that the function To_C maps between the Ada type Wide_Character
-- and the C type wchar_t.
--
-- Check that the function To_Ada maps between the C type wchar_t and
-- the Ada type Wide_Character.
--
-- Check that the function Is_Nul_Terminated returns True if the
-- wchar_array parameter contains wide_nul, and otherwise False.
--
-- Check that the function To_C produces a correct wchar_array result,
-- with lower bound of 0, and length dependent upon the Item and
-- Append_Nul parameters.
--
-- Check that the function To_Ada produces a correct wide_string result,
-- with lower bound of 1, and length dependent upon the Item and
-- Trim_Nul parameters.
--
-- Check that the function To_Ada raises Terminator_Error if the
-- parameter Trim_Nul is set to True, but the actual Item parameter
-- does not contain the wide_nul wchar_t.
--
-- TEST DESCRIPTION:
-- This test uses a variety of Wide_Character, wchar_t, Wide_String, and
-- wchar_array objects to test versions of the To_C, To_Ada, and
-- Is_Nul_Terminated functions.
--
-- This test assumes that the following characters are all included
-- in the implementation defined type Interfaces.C.wchar_t:
-- ' ', ',', '.', '0'..'9', 'a'..'z' and 'A'..'Z'.
--
-- APPLICABILITY CRITERIA:
-- This test is applicable to all implementations that provide
-- package Interfaces.C. If an implementation provides
-- package Interfaces.C, this test must compile, execute, and
-- report "PASSED".
--
-- SPECIAL REQUIREMENTS:
-- The file CXB30060.C must be compiled with a C compiler.
-- Implementation dialects of C may require alteration of
-- the C program syntax (see individual C files).
--
-- Note that the compiled C code must be bound with the compiled Ada
-- code to create an executable image. An implementation must provide
-- the necessary commands to accomplish this.
--
-- Note that the C code included in CXB30060.C conforms
-- to ANSI-C. Modifications to these files may be required for other
-- C compilers. An implementation must provide the necessary
-- modifications to satisfy the function requirements.
--
-- TEST FILES:
-- The following files comprise this test:
--
-- CXB30060.C
-- CXB30061.AM
--
-- CHANGE HISTORY:
-- 07 Sep 95 SAIC Initial prerelease version.
-- 09 May 96 SAIC Incorporated reviewer comments for ACVC 2.1.
-- 13 Sep 99 RLB Replaced (bogus) Unchecked_Conversions with a
-- C function character generator.
