Hi,

I'm using curl to get a video stream. This video stream can send frame very
slowly (for example one frame every 10 minutes).
So i disabled the timeout because i don't want to receive an error if i
don't receive any frame. Nevertheless, this lead to not receive any error
is the connection is lost (for example, if the ethernet cable is
unplugged), and the curl_easy_perform function doesn't abort.

How can I use libcurl to handle that case, where timeout is disabled but
error occurs on connection error.

Here the option i use on Linux 3.2.0-4-amd64 in Mint LMDE:

            // set URL to get
            curl_easy_setopt(pCurlHandle, CURLOPT_URL, szMRL);

            // no progress meter please
            curl_easy_setopt(pCurlHandle, CURLOPT_NOPROGRESS, 0L);

            // Force to don't use cached connection
            curl_easy_setopt(pCurlHandle, CURLOPT_FRESH_CONNECT, 0);
            curl_easy_setopt(pCurlHandle, CURLOPT_FORBID_REUSE, 0);

            // disable timeout that can raise signal
            curl_easy_setopt(pCurlHandle, CURLOPT_NOSIGNAL, 1L);
            curl_easy_setopt(pCurlHandle, CURLOPT_TIMEOUT, 0);
            curl_easy_setopt(pCurlHandle, CURLOPT_CONNECTTIMEOUT, 0);

            // send all data to this function
            curl_easy_setopt(pCurlHandle, CURLOPT_HEADERFUNCTION,
onWriteHeader);
            curl_easy_setopt(pCurlHandle, CURLOPT_WRITEHEADER, pContext);

            // send all data to this function
            curl_easy_setopt(pCurlHandle, CURLOPT_WRITEFUNCTION,
onWriteData);
            curl_easy_setopt(pCurlHandle, CURLOPT_WRITEDATA, pContext);

            // Set progress function
            curl_easy_setopt(pCurlHandle, CURLOPT_PROGRESSFUNCTION,
onProgress);
            curl_easy_setopt(pCurlHandle, CURLOPT_PROGRESSDATA, pContext);

Thank you for your help.
