Hi Yang

Is it better to call SAFE_TOUCH(TESTFILE, 0644, NULL) here?
In this case, we can drop cleanup() as well.
Other than that, it looks good to me.

- * Test Name : symlink04
- *
- * Test Description :
- *  Verify that, symlink will succeed to creat a symbolic link of an existing
- *  object name path.
- *
- * Expected Result:
- *  symlink() should return value 0 on success and symbolic link of an
- *  existing object should be created.
- *
- * Algorithm:
- *  Setup:
- *   Setup signal handling.
- *   Create temporary directory.
- *   Pause for SIGUSR1 if option specified.
- *
- *  Test:
- *   Loop if the proper options are given.
- *   Execute system call
- *   Check return code, if system call failed (return=-1)
- *   	Log the errno and Issue a FAIL message.
- *   Otherwise,
- *   	Verify the Functionality of system call
- *      if successful,
- *      	Issue Functionality-Pass message.
- *      Otherwise,
- *		Issue Functionality-Fail message.
- *  Cleanup:
- *   Print errno log and/or timing stats if options given
- *   Delete the temporary directory created.
- *
- * Usage:  <for command-line>
- *  symlink04 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t]
- *	where,  -c n : Run n copies concurrently.
- *		-e   : Turn on errno logging.
- *		-f   : Turn off functionality Testing.
- *		-i n : Execute test n times.
- *		-I x : Execute test for x seconds.
