Hi Daniel, > Which libcurl version on which platform is this? [Vaibhav] Libcurl version 7.58 Used on Embedded Linux platform on ar758x board.

If there is disconnection with file server (due to any reason), I was expecting error return so that application can restart file transfer. e.g. In this function callback "writeCallback", error return was expected. curl_easy_setopt( l_easy, CURLOPT_WRITEFUNCTION, (curl_write_callback)[](auto a_data, auto, auto a_size, auto a_client) { return CURL_CLIENT(a_client)->writeCallback(a_data, a_size); }); curl_easy_setopt(l_easy, CURLOPT_WRITEDATA, this); > Is this an upload or a download?

That's a bug then. Either in your code or in libcurl. Which libcurl version on which platform is this? > Thus, CURL is not attempting reconnection to resume file transfer. libcurl will not reconnect nor resume anything on error. It should return an error. > Steps: successful connection to file server (filezilla) with valid > credentials File transfer started possible FTP disconnection and file > transfer is aborted. Is this an upload or a download? Exactly how is that "FTP disconnection" done? Can you provide a small stand-alone example program that reproduces the problem? -- / daniel.haxx.se | Commercial curl support up to 24x7 is available! | Private help, bug fixes, support, ports, new features | https://curl.se/support.html ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.se/mail/etiquette.html
