Anything that touches bufferevent internals is going to get you potentially unpredicted results. Right now the best way to do what you have in mind is to consider *why* you only want to read partial data and then read again after the next event loop -- there's usually a better way to do whatever you're trying to achieve. But if there isn't, and you want to make sure your code works with future versions of Libevent, your best bet is either to add a feature like this in Libevent 2.1, or to create a separate event whose callback will also run the bufferevent's callback, and activate that one. hth, -- Nick
