I download multiple files simultaneously with curl_multi_perform
How can I detect if connection is lost during the downloading?
When I simulate the lost connection (disconnecting wi-fi)
select(maxfd+1, &fdread, &fdwrite, &fdexcep, &timeout);
returns 0, but it also returns 0 right before the beginning of downloading.
If I connect back, then the downloading resumes but eventually a file turns
out to be corrupted.
