/*
* NAME
* fchdir02.c
*
* DESCRIPTION
* fchdir02 - try to cd into a bad directory (bad fd).
*
* CALLS
* fchdir()
*
* ALGORITHM
* loop if that option was specified
* call fchdir() with an invalid file descriptor
* check the errno value
* issue a PASS message if we get EBADF - errno 9
* otherwise, the tests fails
* issue a FAIL message
* break any remaining tests
* call cleanup
*
* USAGE: <for command-line>
* fchdir02 [-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
* 03/2001 - Written by Wayne Boyer
*
* RESTRICTIONS
* none
