At some point during 2003, my friend Bjørn (from Dancer) and I were discussing back and forth and planning to maybe create our own asynchronous DNS/name resolver library. We felt that the synchronous APIs provided by
getaddrinfo()were too limiting in for example curl. We could really use something that would not block the caller.
While thinking about this and researching what was already out there, I found the ares library written by Greg Hudson. It was an effort that was almost exactly what we had been looking for. I decided I would not make a new library but rather join the ares project and help polish that further to perfect it for curl.
It was soon made clear to me that the original author of this library did not want the patches I deemed were necessary, including changes to make it more portable to Windows and beyond. I felt I had no choice but to fork the project and instead I created c-ares. It would show its roots but not be the same. The
ccould be for curl, but it also made it into an English word like "cares" which was enough for me.
The first c-ares release I did was called version 1.0.0, published in February 2004.
With c-ares, we could soon offer asynchronous name resolving for curl on a wide range of platforms, but of course there were other projects and users out in the world who felt a similar need. c-ares is deployed widely by many.
I have tried to reduce my own personal activities in the c-ares project the last few years simply because I feel I do not have enough time and energy to keep it up in this project as well. I still am a maintainer but I am not doing a lot.
