* NAME

|
* signal02.c
|
|
*
|
|
* DESCRIPTION
|
|
* signal02 - Test that we get an error using illegal signals
|
|
*
|
|
* ALGORITHM
|
|
* loop if that option was specified
|
|
* issue the system call
|
|
* check the return value
|
|
* if return value != -1
|
|
* issue a FAIL message, break remaining tests and cleanup
|
|
* if we get an EINVAL
|
|
* issue a PASS message
|
|
* else
|
|
* issue a FAIL message, break remaining tests and cleanup
|
|
* call cleanup
|
|
*
|
|
* USAGE: <for command-line>
|
|
* signal02 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -e : Turn on error logging.
|
|
* -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.
