Have I > misunderstood something? I understand it as: Since _even_ with edge-triggered epoll [and thus also with other epolls], multiple events can be generated ... the stuff after the comma applied to at least more than one epoll typer.; That's maybe why it's so generic. However, I think a clarification like to one you suggest could be appropriate in the page. I've added Michael to this mail, who may be better placed to help with these APIs. Have a lovely day!
