- * OS Test - Silicon Graphics, Inc.
- *
- * 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:
