* 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.
