| * 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. Call pthread_mutexattr_getprioceiling() to obtain the prioceiling. |
