! @typedef pthread_override_t

@abstract An opaque object representing a QOS class override of a thread.

@discussion A QOS class override of a target thread expresses that an item of pending work classified with a specific QOS class and relative priority depends on the completion of the work currently being executed by the thread (e.g. due to ordering requirements).

While overrides are in effect, the target thread will execute at the maximum QOS class and relative priority of all overrides and of the QOS class requested by the thread itself.

A QOS class override does not modify the target thread's requested QOS class value and the effect of an override is not visible to the qos_class_self() and pthread_get_qos_class_np() interfaces.
