/*
* Test Name : symlink02
*
* Test Description :
* Verify that, symlink will succeed to creat a symbolic link of an
* non-existing object name path.
*
* Expected Result:
* symlink() should return value 0 on success and symlink of an
* non-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>
* symlink02 [-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.
* -P x : Pause for x seconds between iterations.
* -t : Turn on syscall timing.
*
* History
* 07/2001 John George
* -Ported
*
* Restrictions:
* This test should be run by 'non-super-user' only.
*
