|
* NAME
|
|
* setpgid02.c
|
|
*
|
|
* DESCRIPTION
|
|
* Testcase to check that setpgid() sets errno correctly.
|
|
*
|
|
* CALLS
|
|
* setpgid
|
|
*
|
|
* ALGORITHM
|
|
* Checks that setpgid returns the correct errno values in case of
|
|
* negative testing.
|
|
* test 1: EINVAL - Pass '-1' as the pgid parameter to setpgid
|
|
* test 2: ESRCH - Pass '-1' as the pid parameter to setpgid
|
|
* test 3: EPERM - Pass an invalid pgid parameter to setpgid
|
|
*
|
|
* USAGE: <for command-line>
|
|
* setpgid02 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -e : Turn on errno 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.
