/*
* NAME
* fchdir01.c
*
* DESCRIPTION
* fchdir01 - create a directory and cd into it.
*
* ALGORITHM
* create a new directory
* open the directory and get a file descriptor
* loop if that option was specified
* fchdir() into the directory
* check the return code
* if failure, issue a FAIL message.
* otherwise,
* if doing functionality testing, call check_functionality()
* if correct,
* issue a PASS message
* otherwise
* issue a FAIL message
* call cleanup
*
* USAGE: <for command-line>
* fchdir01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
* where, -c n : Run n copies concurrently.
* -f : Turn off functionality Testing.
* -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
