Hi,
I need a proper solution to cancel curl_easy_perform that is running on a separate thread. My initial approach was to save the handle, then on the main thread, try to interfere it by , e.g.
curl_easy_setopt(m_sseHandle, CURLOPT_TIMEOUT_MS, 1);
It did work, but then i read below it's unsafe to access the same handle across different threads.
Are the points in this posting (from 13 years ago) still valid?

Questions:
* is it still unsafe to use the same handle in more than 1 thread?
* is the progress callback the only proper way to cancel curl_easy_perform? It works, but there's overhead of the callback being triggered every second.
Please advise, i very much need a solution soon. Thank you so much for your attention.
Regards,
Winnie
