| * TEST IDENTIFIER : alarm02 |
| * |
| * TEST TITLE : Boundary Value Test for alarm(2) |
| * |
| * PARENT DOCUMENT : almtds02 |
| * |
| * TEST CASE TOTAL : 3 |
| * |
| * WALL CLOCK TIME : 1 |
| * |
| * CPU TYPES : ALL |
| * |
| * AUTHOR : Billy Jean Horne |
| * |
| * CO-PILOT : Kathy Olmsted |
| * |
| * DATE STARTED : 06/01/92 |
| * |
| * INITIAL RELEASE : UNICOS 7.0 |
| * |
| * TEST CASES |
| * Test Case One - A call to alarm() shall not return an error if |
| * seconds is a -1. |
| * Test FAILS if a non-zero value is returned. |
| * Test Case Two - A call to alarm() shall not return an error if |
| * seconds is the maximum unsigned integer (2**63). |
| * Test FAILS if a non-zero value is returned. |
| * Test Case Three - A call to alarm() shall not return an error if |
| * seconds is the maximum unsigned integer plus 1 ((2**63)+1). |
| * Test FAILS if a non-zero value is returned. |
| * |
| * ENVIRONMENTAL NEEDS |
| * The libcuts.a and libsys.a libraries must be included in |
| * the compilation of this test. |
| * |
| * DETAILED DESCRIPTION |
| * |
| * Setup: |
| * Define a cleanup function. |
| * |
| * Test: |
| * Loop for each test case. |
| * Execute alarm (0) system call to clear previous alarm. |
| * Check return code, if system call failed (return=-1) |
| * Issue a FAIL message and exit the test. |
| * Call alarm() with boundary values for seconds. |
| * Verify that returned value is as expected. |
| * Report results. |
| * |
| * Cleanup: |
