| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that the procedure To_C converts the character elements of |
| -- a string parameter into char elements of the char_array parameter |
| -- Target, with nul termination if parameter Append_Nul is true. |
| -- |
| -- Check that the out parameter Count of procedure To_C is set to the |
| -- appropriate value for both the nul/no nul terminated cases. |
| -- |
| -- Check that Constraint_Error is propagated by procedure To_C if the |
| -- length of the char_array parameter Target is not sufficient to |
| -- hold the converted string value. |
| -- |
| -- Check that the Procedure To_Ada converts char elements of the |
| -- char_array parameter Item to the corresponding character elements |
| -- of string out parameter Target. |
| -- |
| -- Check that Constraint_Error is propagated by Procedure To_Ada if the |
| -- length of string parameter Target is not long enough to hold the |
| -- converted char_array value. |
| -- |
| -- Check that Terminator_Error is propagated by Procedure To_Ada if the |
| -- parameter Trim_Nul is set to True, but the actual Item parameter |
| -- contains no nul char. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test uses a variety of String, and char_array objects to test |
| -- versions of the To_C and To_Ada procedures. |
| -- |
| -- 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. 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. |
