/**********************************************************
*
* 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
*
* BINARY LOCATION : CUTS_BIN/rf_tests/sys
*
* SOURCE LOCATION : CUTS_SRC/src/tests/sys
*
* 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 BROK message and exit the test.
* Call alarm() with boundary values for seconds.
* Verify that returned value is as expected.
* Report results.
*
* Cleanup:
