- * 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.
+/*\
+ * [Description]
*
- * 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
+ * Check that only the root process can invoke setgroups()
+ * to set supplementary group IDs.
*
- * 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.
+ * [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.
