It sounds like "latch" is basically the same thing as an "event" (as in CreateEvent() in Windows, eventfd in Linux), but maybe optimized for single-process usage? Edit: Ok so a (Windows) event is one bit, a C++ latch is a one-shot counter, and a C++ barrier is a cyclic counter. But I thought a barrier in general computer science terms is just a one-shot counter, which is what they're calling a latch in C++?
