8 * Test that pthread_mutex_timedlock()
9 *
10 * It SHALL fail if:
11 *
12 * [EINVAL] - The process or thread would have blocked, and the abs_timeout parameter
13 *	     specified in nano-seconds field value is less than 0 or greater than or equal
14 * 	     to 1,000 million.
15 *
16 * Steps:
17 *
18 * 1. Create a thread.
19 * 2. Call pthread_mutex_timedlock inside of the thread passing to it a negative number in the
20 *    nano-seconds field of the 'abs_timeout'.
21 * 3. Save the return value of pthread_mutex_timedlock().  It should be EINVAL.
