* NAME
|
|
* signal05.c
|
|
*
|
|
* DESCRIPTION
|
|
* signal05 - set the signal handler to our own function
|
|
*
|
|
* 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 are doing functional testing
|
|
* send the signal with kill()
|
|
* if we catch the signal in the signal handler
|
|
* issue a PASS message
|
|
* else
|
|
* issue a FAIL message
|
|
* call cleanup
|
|
*
|
|
* USAGE: <for command-line>
|
|
* signal05 [-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.
