| /* |
| * 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. |
