1) Remove uclinux code
2) Take use of safe macro
3) Merge kill04 into kill03
4) Add error test that pid is INT_MIN

- * NAME
- * kill03.c
- *
- * DESCRIPTION
- * Test case to check that kill fails when given an invalid signal.
- *
- * ALGORITHM
- * call setup
- * loop if the -i option was given
- * fork a child
- * execute the kill system call with an invalid signal
- * check the return value
- * if return value is not -1
- * issue a FAIL message, break remaining tests and cleanup
- * if we are doing functional testing
- * if the errno was set to 22 (invalid argument).
- * issue a PASS message
- * otherwise
- * issue a FAIL message
- * call cleanup
- *
- * USAGE
- * kill03 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
- * where, -c n : Run n copies concurrently.
- * -f : Turn off functionality Testing.
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
+ * 1) kill() fails with errno set to EINVAL if given an invalid signal.
+ * 2) kill() fails with errno set to ESRCH if given a non-existent pid.
+ * 3) kill() fails with errno set to ESRCH if the given pid is INT_MIN.
