     56  *
     57  *    TEST CASES
     58  *      Test Case One - A call to alarm() shall not return an error if
     59  *       seconds is a -1.
     60  *       Test FAILS if a non-zero value is returned.
     61  *      Test Case Two - A call to alarm() shall not return an error if
     62  *       seconds is the maximum unsigned integer (2**63).
     63  *       Test FAILS if a non-zero value is returned.
     64  *      Test Case Three - A call to alarm() shall not return an error if
     65  *       seconds is the maximum unsigned integer plus 1 ((2**63)+1).
     66  *       Test FAILS if a non-zero value is returned.
     67  *
     68  *    ENVIRONMENTAL NEEDS
     69  *      The libcuts.a and libsys.a libraries must be included in
     70  *      the compilation of this test.
     71  *
     72  *    DETAILED DESCRIPTION
     73  *
     74  *      Setup:
     75  *        Define a cleanup function.
     76  *
     77  *      Test:
     78  *       Loop for each test case.
     79  *        Execute alarm (0) system call to clear previous alarm.
     80  *        Check return code, if system call failed (return=-1)
     81  *           Issue a FAIL message and exit the test.
     82  *        Call alarm() with boundary values for seconds.
     83  *        Verify that returned value is as expected.
     84  *        Report results.
     85  *
     86  *      Cleanup:
