 /*
  * Test Name: utime04
  *
  * Test Description:
  *  Verify that the system call utime() successfully sets the modification
  *  and access times of a file to the time specified by times argument, if
  *  the times argument is not null, and the user ID of the process is "root".
  *
  * Expected Result:
  *   utime succeeds returning zero and sets the access and modification
  *   times of the file to that specified by the times argument.
  *
  * 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>
  *  utime04 [-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 'super-user' (root) only.
