Feedback as one of the more recent multi-users: - once I read the documentation, it was quite easy to figure out X-) - I find the way of stuffing several easy things into one multi quite intuitive. - there are several use scenarios that can be described as "async" * mine was a pretty simple one where libcurl is selecting itself and there are no handles from somewhere else to watch * I therefore cannot speak on how easy it is to integrate curl handles into your own select/poll/whatever
As a related, but slightly different thought: - the API offered by libnghttp2 has one important feature: it does not do IO itself - it could be an idea to offer a curl API that gets fed with chunks of data to process and hands out other chunks to send. - this would decouple big parts of curl from socket/file handles and would let applications use whatever fits them best (of course, the existing API should stay) My quick, off the hip, thoughts about this...
