 * Test that pthread_condattr_setclock()
 *
 *  If it is called with a clock_id argument that refers to a CPU-time clock, the call
 *  shall fail.
 *
 * Steps:
 * 1.  Initialize a pthread_condattr_t object
 * 2.  Get the cpu clock id
 * 3.  Call pthread_condattr_setclock passing this clock id to it
 * 4.  It should fail.
