  o, you are right, there's no definition for such a network, i used the
wrong description. what i mean is "when network is broken, the function
curl_easy_perform is not return and the CURLOPT_WRITEFUNCTION callback
is not receive data anymore, that is the callback will be not used anymore,
so i can't actively abort the operation, is there any other callback i
can use to make the curl_easy_perform return immediately when the network is
broken?
