+--*
+--
+-- OBJECTIVE:
+--      Check that the version of Function Value with a chars_ptr parameter
+--      that returns a String result returns an Ada string containing the
+--      characters pointed to by the chars_ptr parameter, up to (but not 
+--      including) the terminating nul.
+--
+--      Check that the version of Function Value with a chars_ptr parameter
+--      and a size_t parameter that returns a String result returns the
+--      shorter of: 
+--        1) a String of the first size_t number of characters, or 
+--        2) a String of characters up to (but not including) the
+--           terminating nul.
+--
+--      Check that the Function Strlen returns a size_t result that
+--      corresponds to the number of chars in the array pointed to by Item,
+--      up to but not including the terminating nul.
+--
+--      Check that both of the above versions of Function Value and
+--      Function Strlen propagate Dereference_Error if the Item parameter
+--      is Null_Ptr.
+--      
+-- TEST DESCRIPTION:
+--      This test validates two versions of Function Value, and the Function
+--      Strlen.  A series of char_ptr values are provided as input, and 
+--      results are compared for length or content.  
+--      
+--      This test assumes that the following characters are all included
+--      in the implementation defined type Interfaces.C.char:
+--      ' ', 'a'..'z', 'A'..'Z', '0'..'9', '*' and '.'.
+--      
+-- APPLICABILITY CRITERIA: 
+--      This test is applicable to all implementations that provide 
+--      package Interfaces.C.Strings.  If an implementation provides
+--      package Interfaces.C.Strings, this test must compile, execute, 
+--      and report "PASSED".
