/*
* NAME
* open02.c
*
* DESCRIPTION
* Test if open without O_CREAT returns -1 if a file does not exist.
*
* ALGORITHM
* 1. open a new file without O_CREAT, test for return value of -1
*
* USAGE: <for command-line>
* open02 [-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 Ported by Wayne Boyer
*
* RESTRICTIONS
* None
