| --* |
| -- |
| -- 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". |
