* 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.
