| /* |
| * Test Name: chmod07 |
| * |
| * Test Description: |
| * Verify that, chmod(2) will succeed to change the mode of a file/directory |
| * and sets the sticky bit on it if invoked by root (uid = 0) process with |
| * the following constraints, |
| * - the process is not the owner of the file/directory. |
| * - the effective group ID or one of the supplementary group ID's of the |
| * process is equal to the group ID of the file/directory. |
| * |
| * Expected Result: |
| * chmod() should return value 0 on success and succeeds to set sticky bit |
| * on the specified file. |
| * |
| * Algorithm: |
| * Setup: |
| * Setup signal handling. |
| * Create temporary directory. |
| * 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 |
| * Delete the temporary directory created. |
| * |
| * Usage: <for command-line> |
| * chmod07 [-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. |
