[LAD] [ot] efficient (event)-loop writing

Hello everyone! I have a problem and I'm not sure how to solve it in an optimal way. I have several threads running. 1. An input thread (computer-keyboard/mouse) 2. An output thread (monitor other devices0 3. A working thread (the engine) Now I wondered, what is the most efficient way to write the loops for the input and output threads in a way, that they are always ready to accept something coming. I thought about something with signals, which is fine, as far as the output is concerned, but the input comes from the user and only the device gets it coming first and it can't really send a signal? Any tipps, good guide or constructs, which have proven to be efficient?
