- * 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
+/*\
+ * [DESCRIPTION]
*
- * RESTRICTIONS
- * None.
+ * Verify that rename(2) fails and errno is set to EFAULT, when
+ * oldpath or newpath points outside of accessible address space.
