Classes
class	dx::usb::stream::pipe< device_t, circular_t, stream_t >
	one isochronous endpoint as a stream: the ring, the cycle of slots the session rotates through and the thread that ticks them. The data path itself is dx::usb::isoc::pipeline, shared with the kernel driver; this class supplies its platform part - a slot's request over its buffer, the completions in submission order, the direction's data event and the timestamp clock. An asynchronous sink keeps its sync endpoint's requests here too (isoc.sync), an implicit feedback source reads its rate off its own delivered lines. More...
struct	dx::usb::stream::pipe< device_t, circular_t, stream_t >::cache
	what the tick reads instead of asking a promoted: the derived transaction sizes, the encoder stages and the in slot's sentinel - none of them may block or lock More...
struct	dx::usb::stream::pipe< device_t, circular_t, stream_t >::cache::encoder
struct	dx::usb::stream::pipe< device_t, circular_t, stream_t >::isoc
	what this pipe's session needs beside its own requests: the feedback ring of lines per frame, and an explicit feedback endpoint's own slots More...
