/*
* 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.
*
* History
* 07/2001 John George
* -Ported
*
* Restrictions
* None
