/*
* NAME
* rename08
*
* DESCRIPTION
* This test will verify that rename(2) syscall failed in EFAULT
*
* ALGORITHM
* Setup:
* Setup signal handling.
* Create temporary directory.
* Pause for SIGUSR1 if option specified.
* Create a valid file to use in the rename() call.
*
* Test:
* Loop if the proper options are given.
* 1. "old" is a valid file, newpath points to address
* outside allocated address space
* rename the "old" to the "new" file
* verify rename() failed with error EFAULT
*
* 2. "old" points to address outside allocated address space
* ,"new" is a valid file
* rename the "old" to the "new"
* verify rename() failed with error EFAULT
*
* 3. oldpath and newpath are all NULL
* try to rename NULL to NULL
* verify rename() failed with error EFAULT
* Cleanup:
* Print errno log and/or timing stats if options given
* Delete the temporary directory created.*
* USAGE
* rename08 [-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.
