/*
* NAME
* close02.c
*
* DESCRIPTION
* Check that an invalid file descriptor returns EBADF
*
* ALGORITHM
* loop if that option is specified
* call close using the TEST macro and passing in an invalid fd
* if the call succeedes
* issue a FAIL message
* else
* log the errno
* if the errno == EBADF
* issue a PASS message
* else
* issue a FAIL message
* cleanup
*
* USAGE: <for command-line>
* close02 [-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
