******************************************************************

TEST: 1-1.c
 * Test that timer_create() creates a timer.
 * Steps:
 * 1.  Set up sigevent structure to send signal SIGTOTEST on timer
 *     expiration.
 * 2.  Set up sigaction structure to catch signal SIGTOTEST on timer
 *     expiration
 * 3.  Create timer using timer_create().
 * 4.  Activate timer using timer_settime() and then sleep.
 * 5.  If signal handler is called, continue.  Otherwise, fail.
 * 6.  If signal handler was called and the time left in sleep ~= the
 *     delta between the timer time and sleep time, then PASS.
 *     Otherwise, FAIL.
 *
 * For this test, signal SIGTOTEST will be used, clock CLOCK_REALTIME
 * will be used.

******************************************************************

TEST: 16-1.c
 * Test that timer_create() sets errno to EINVAL if clock_id is not
 * a defined clock ID.

******************************************************************

TEST: 2-1.c
 * Test that timer_create() returns a unique timer ID for the current
 * process.
 * For this test, signal SIGALRM will be used, clock CLOCK_REALTIME
 * will be used.

******************************************************************

TEST: 5-1.c
 * Test that the following scenarios are identical:
 * evp == NULL
 * and
 * evp.sigev_notify=SIGEV_SIGNAL
 * evp.sigev_signo="default signal"
 * evp.sigev_value=timerid
 *
 * Steps:
 * 1.  Set up sigaction structure to catch signal SIGALRM (default signal) on 
 *     timer expiration
 * 2.  Create timer using timer_create().
 * 3.  Activate timer using timer_settime() and then sleep.
 * 4.  If signal handler is called, continue.  Otherwise, fail.
 * 5.  If signal handler was called and the time left in sleep ~= the
 *     delta between the timer time and sleep time, then PASS.
 *     Otherwise, FAIL.
 *
 * Note:  This test is identical to 1-1.c minus the evp lines.
 *
 * For this test clock CLOCK_REALTIME will be used.

******************************************************************

TEST: 7-1.c
 * pt:MON
 *
 * Test that CLOCK_MONOTONIC is supported by timer_create().
 *
 * Same test as 1-1.c with CLOCK_MONOTONIC.
