| 23 | * Test Description: |
| 24 | * Verify that, chmod(2) will succeed to change the mode of a file/directory |
| 25 | * and sets the sticky bit on it if invoked by root (uid = 0) process with |
| 26 | * the following constraints, |
| 27 | * - the process is not the owner of the file/directory. |
| 28 | * - the effective group ID or one of the supplementary group ID's of the |
| 29 | * process is equal to the group ID of the file/directory. |

| 32 | * chmod() should return value 0 on success and succeeds to set sticky bit |
| 33 | * on the specified file. |
| 34 | * |
| 35 | * Algorithm: |
| 36 | * Setup: |
| 37 | * Setup signal handling. |
| 38 | * Create temporary directory. |
| 39 | * Pause for SIGUSR1 if option specified. |
| 40 | * |
| 41 | * Test: |
| 42 | * Loop if the proper options are given. |
| 43 | * Execute system call |
| 44 | * Check return code, if system call failed (return=-1) |
| 45 | * Log the errno and Issue a FAIL message. |
| 46 | * Otherwise, |

| 49 | * Issue Functionality-Pass message. |
| 50 | * Otherwise, |
| 51 | * Issue Functionality-Fail message. |
| 52 | * Cleanup: |
| 53 | * Print errno log and/or timing stats if options given |
| 54 | * Delete the temporary directory created. |
