I updated my libcurl to 7.65.3 and at the same time I found out that the 3rd party sdk i am using does use curl_easy_setopt(curl, CURLOPT_NOSIGNAL, 1). After I set that to "0" my program didn't terminate when wifi was switched off. But from the brief reading on google , it seems that CURLOPT_NOSIGNAL should be set to 1 for multithreaded applications like mine. Is there a way to keep CURLOPT_NOSIGNAL = 1 and handle the broken SIGPIPE problem I am getting originally?
