A variety of char_array and char_ptr values are provided as --- input, and results are compared for both length and content. --- --- This test assumes that the following characters are all included --- in the implementation defined type Interfaces.C.char: --- ' ', 'a'..'z', and 'A'..'Z'. --- --- 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". --- --- --- CHANGE HISTORY: --- 27 Sep 95 SAIC Initial prerelease version. --- 13 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. --- 26 Oct 96 SAIC Incorporated reviewer comments. --- 01 DEC 97 EDS Replicate line 199 at line 256, to ensure that --- TC_chars_ptr has a valid pointer. --- 08 JUL 99 RLB Added a test case to check that Value raises --- Constraint_Error when Length = 0.
