| * NAME |
| * umask02.c |
| * |
| * DESCRIPTION |
| * Check that umask changes the mask, and that the previous |
| * value of the mask is returned correctly for each value. |
| * |
| * ALGORITHM |
| * For each mask value (9 bits) set mask, and check that the return |
| * corresponds to the previous value set. |
| * |
| * USAGE: <for command-line> |
| * umask02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -e : Turn on errno logging. |
| * -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 John George |
| * -Ported |
| * |
| * Restrictions |
| * None |
