Is there any simple way to implement the async cancel in this case - by using another callback for example?
No and yes. libcurl offers a wide variety of callbacks and most or all of them can cancel the operation. None of them are "instant" however so if you want a GUI or similar to get a feeling of instant reward I generally advice that you let the current thread take its time to stop (be it one second or three, it doesn't matter) and you start a new one for the next operation and thus the user won't know nor "feel" the non-instantness of libcurl's cancel.
I saw that c-ares can be used for async dns lookup, but I'd rather not add yet another dependency to all the projects I already maintain. Besides, I couldn't find any info in the libcurl documentation on how to actually add c-ares support.
Define USE_ARES when you build libcurl.
BTW, I sent a link to be inserted in your directory of libcurl powered apps a while ago, but it was never listed. Are there any special requirements for that?
Hm, I must've missed that! Please mail me again with the details... -- / daniel.haxx.se ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
