mm::comm::spoe::SpoeOutputSlot Class Reference

#include <spoe_process_data.h>

Public Member Functions
void	reset (std::size_t frameBytes)
	Sizes every buffer and clears them. Not safe while the writer or the reader runs.
void	write (std::span< const uint8_t > frame)
	Writer side. frame must hold the size given to reset.
std::span< const uint8_t >	read ()
	Reader side. Returns the newest frame, or the previous one again when nothing newer arrived.

Detailed Description

Hands the newest output frame from one writer to one reader. Three buffers: the writer fills its own and swaps it with the middle one, and the reader swaps the middle one with its own when a newer frame is there. Neither side waits, and neither side sees a half-written frame.
