* AUTHOR : Billy Jean Horne

|
|
* 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 BROK message and exit the test.
|
|
* Call alarm() with boundary values for seconds.
|
|
* Verify that returned value is as expected.
|
|
* Report results.
|
|
*
|
|
* Cleanup:
