 * Test that pthread_mutexattr_setprioceiling()
 *
 * It MAY fail if:
 *
 * [EINVAL] - 'attr' or 'prioceiling' is invalid.
 * [EPERM] - The caller doesn't have the privilege to perform the operation.
 *
 * Steps:
 * 1.  Initialize a pthread_mutexattr_t object with pthread_mutexattr_init()
 * 2.  Call pthread_mutexattr_setprioceiling() to set the prioceiling.
