/*
* NAME
* rename01
*
* DESCRIPTION
* This test will verify the rename(2) syscall basic functionality.
* Verify rename() works when the "new" file or directory does not exist.
*
* ALGORITHM
* Setup:
* Setup signal handling.
* Create temporary directory.
* Pause for SIGUSR1 if option specified.
*
* Test:
* Loop if the proper options are given.
* 1. "old" is plain file, new does not exists
* create the "old" file, make sure the "new" file
* dose not exist
* rename the "old" to the "new" file
* verify the "new" file points to the "old" file
* verify the "old" file does not exist
*
* 2. "old" is a directory,"new" does not exists
* create the "old" directory, make sure "new"
* dose not exist
* rename the "old" to the "new"
* verify the "new" points to the "old"
* verify the "old" does not exist
* Cleanup:
* Print errno log and/or timing stats if options given
* Delete the temporary directory created.
*
* USAGE
* rename01 [-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.
