/*
* Test Name: setgroups02
*
* Test Description:
* Verify that, only root process can invoke setgroups() system call to
* set the supplementary group IDs of the process.
*
* Expected Result:
* The call succeeds in setting all the supplementary group IDs of the
* calling process. The new group should be set in the process supplemental
* group list.
*
* Algorithm:
* Setup:
* Setup signal handling.
* Pause for SIGUSR1 if option specified.
*
* Test:
* Loop if the proper options are given.
* Execute system call
* Check return code, if system call failed (return=-1)
* Log the errno and Issue a FAIL message.
* Otherwise,
* Verify the Functionality of system call
* if successful,
* Issue Functionality-Pass message.
* Otherwise,
* Issue Functionality-Fail message.
* Cleanup:
* Print errno log and/or timing stats if options given
*
* Usage: <for command-line>
* setgroups02 [-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 run by 'super-user' (root) only.
