Cancel libcurl easy handle

问题

Is there an easy way to cancel a curl_easy_perform from another thread?

回答1:

You have to use the callback functions (write/read/progress) to perform the cancel. The other thread needs to set a flag and the callback function checks the flag and returns the proper value to cancel the operation.
