-/**********************************************************
- *
- *    TEST IDENTIFIER	: capset01
- *
- *    EXECUTED BY	: anyone
- *
- *    TEST TITLE	: Basic test for capset(2)
- *
- *    TEST CASE TOTAL	: 1
- *
  *    AUTHOR		: Saji Kumar.V.R <saji.kumar@wipro.com>
  *
- *    SIGNALS
- * 	Uses SIGUSR1 to pause before test if option set.
- * 	(See the parse_opts(3) man page).
- *
- *    DESCRIPTION
- *	This is a Phase I test for the capset(2) system call.
- *	It is intended to provide a limited exposure of the system call.
- *
- * 	Setup:
- * 	  Setup signal handling.
- *	  Pause for SIGUSR1 if option specified.
- *	  call capget() to save the current capability data
- *
- * 	Test:
- *	 Loop if the proper options are given.
- * 	  call capset() with the saved data
- *	  if return value == 0
- *		Test passed
- *	  Otherwise
- *		Test failed
- *
- * 	Cleanup:
- * 	  Print errno log and/or timing stats if options given
- *
- * USAGE:  <for command-line>
- * capset01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
- *			where,  -c n : Run n copies concurrently.
- *				-e   : Turn on errno logging.
- *				-h   : Show help screen
- *				-f   : Turn off functional testing
- *				-i n : Execute test n times.
- *				-I x : Execute test for x seconds.
- *				-p   : Pause for SIGUSR1 before starting
- *				-P x : Pause for x seconds between iterations.
- *				-t   : Turn on syscall timing.
- *
  * CHANGES:
  *  2005/01/01: add an hint to a possible solution when test fails
