/*
* NAME
* rename13
*
* DESCRIPTION
* Verify rename() return successfully and performs no other action
* when "old" file and "new" file link to the same file.
*
* ALGORITHM
* Setup:
* Setup signal handling.
* Create temporary directory.
* Pause for SIGUSR1 if option specified.
*
* Test:
* Loop if the proper options are given.
* create the "old" file
* link the "new" file to the "old" file
* rename the "old" to the "new" file
* verify the "new" file points to the original file
* verify the "old" file exists and points to
* the original file
* Cleanup:
* Print errno log and/or timing stats if options given
* Delete the temporary directory created.
*
* USAGE
* rename13 [-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
* 07/2001 Ported by Wayne Boyer
*
* RESTRICTIONS
* None.
