 *    TEST IDENTIFIER	: capget01
 *
 *    EXECUTED BY	: anyone
 *
 *    TEST TITLE	: Basic test for capget(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 capget(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.
 *
 * 	Test:
 *	 Loop if the proper options are given.
 * 	  call capget()
 *	  if return value == 0
 *		Test passed
 *	  Otherwise
 *		Test failed
 *
 * 	Cleanup:
 * 	  Print errno log and/or timing stats if options given
 *
 * USAGE:  <for command-line>
 * capget01 [-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.
