| * Test that pthread_mutexattr_getprioceiling() |
| * |
| * Gets the priority ceiling attribute of a mutexattr object (which was prev. created |
| * by the function pthread_mutexattr_init()). |
| * |
| * Steps: |
| * 1. Initialize a pthread_mutexattr_t object with pthread_mutexattr_init() |
| * 2. Get the min and max boundries for SCHED_FIFO of what prioceiling can be. |
| * 3. In a for loop, go through each valid SCHED_FIFO value, set the prioceiling, then |
| * get the prio ceiling. These should always be the same. If not, fail the test. |
