| 24 | * DESCRIPTION |
| 25 | * Check that umask changes the mask, and that the previous |
| 26 | * value of the mask is returned correctly for each value. |
| 27 | * |
| 28 | * ALGORITHM |
| 29 | * For each mask value (9 bits) set mask, and check that the return |
| 30 | * corresponds to the previous value set. |
| 31 | * |
| 32 | * USAGE: <for command-line> |
