/*
* NAME
* kill01.c
*
* DESCRIPTION
* Test case to check the basic functionality of kill().
*
* ALGORITHM
* call setup
* loop if the -i option was given
* fork a child
* execute the kill system call
* check the return value
* if return value is -1
* issue a FAIL message, break remaining tests and cleanup
* if we are doing functional testing
* if the process was terminated with the expected signal.
* issue a PASS message
* otherwise
* issue a FAIL message
* call cleanup
*
* USAGE
* kill01 [-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.
*
* HISTORY
* 07/2001 Ported by Wayne Boyer
*
* RESTRICTIONS
* This test should be ran as a non-root user.
