Thanks Daniel. I am not pretty sure when you said " you're adding one of those handles twice." What does it mean ? All that I am using is curl_easy_init(), curl_easy_perform(), curl_easy_cleanup APIs.
I am getting the error(easy handled already used in multi handle) when I called curl_easy_init() followed by curl_easy_perform ? Which of these API is adding handles twice to ??? thanks, krishna On Mon, Feb 11, 2019 at 10:48 AM Daniel Stenberg <dan...@haxx.se> wrote: > On Mon, 11 Feb 2019, kishore koney via curl-library wrote: > > > I am using *libcurl(version = 7.61.1*]*)* easy API for downloading http > > url/files(as byte-range chunks).
