 *    TEST IDENTIFIER	: timer_delete03
 *
 *    EXECUTED BY	: anyone
 *
 *    TEST TITLE	: Test checking for basic error conditions for
 *    			  timer_delete(2)
 *
 *    TEST CASE TOTAL	: 1
 *
 *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe@wipro.com>
 *
 *    SIGNALS
 * 	Uses SIGUSR1 to pause before test if option set.
 * 	(See the parse_opts(3) man page).
 *
 *    DESCRIPTION
 *    	This test case check whether timer_delete(2) returns appropriate error
 *    	value for invalid parameter
 *
 * 	Setup:
 *	 Setup signal handling.
 *	 Pause for SIGUSR1 if option specified.
 *
 * 	Test:
 *	 Loop if the proper options are given.
 *	 Execute system call with invalid parameter.
 *	 Check return code, if system call fails with errno == expected errno
 * 	 	Issue syscall passed with expected errno
 *	 Otherwise, Issue syscall failed to produce expected errno
 *
 * 	Cleanup:
 * 	 Print errno log and/or timing stats if options given
 *
 * USAGE:  <for command-line>
 * timer_delete03 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
 * where:
 * 	-c n : run n copies simultaneously
 *	-e   : Turn on errno logging.
 *	-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.
 *
 * RESTRICTIONS:
 * None
