* NAME
|
|
* umask01.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>
|
|
* umask01 [-c n] [-i n] [-I x] [-P x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -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.
