| * 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. |
