I see. So the meaning of the new type is that normal cancellation handling is never triggered, instead the "cancelled" flag can only be polled by the explicit check API. What do cancellable functions do, then? Do they just fail with ECANCELED while leaving the cancelled flag set? I'd call this new type by a name that's descriptive of what it means, rather than what programs are expected to use it. For example, PTHREAD_CANCEL_POLLED. Thanks, Roland
