Hi Daniel,
Thanks for suggestions. We will work on upgrade.
Regarding disconnection, here is code flow -
1. Authentication to server successful.
2. Opening data channel for File download from server
3. after 2 minutes, connection timed out.
Sample code -
initMultiHandle();
// initiate download
auto l_easy = initEasyHandle();
if (l_easy)
{
l_result = curl_multi_add_handle(m_multi, l_easy);
}
else
{
Error
}
bool initMultiHandle()
{
auto l_result = CURLM_OK;
m_multi = curl_multi_init();
curl_multi_setopt(
m_multi, CURLMOPT_SOCKETFUNCTION,
(curl_socket_callback)[](auto, auto a_socket, auto a_action, auto a_client,
auto) {
return CURL_CLIENT(a_client)->socketCallback(a_socket,
a_action);
});
curl_multi_setopt(m_multi, CURLMOPT_SOCKETDATA, this);
curl_multi_setopt(
m_multi, CURLMOPT_TIMERFUNCTION,
(curl_multi_timer_callback)[](auto, auto a_interval, auto a_client) {
return
CURL_CLIENT(a_client)->updateTimeoutCallback(a_interval);
});
curl_multi_setopt(m_multi, CURLMOPT_TIMERDATA, this);
return l_result = CURLM_OK;
}
CURL initEasyHandle()
{
auto l_easy{curl_easy_init()};
// basic stuff
curl_easy_setopt(l_easy, CURLOPT_URL, <URL>);
curl_easy_setopt(l_easy, CURLOPT_USERNAME, <USER>);
curl_easy_setopt(l_easy, CURLOPT_PASSWORD, <PWD>);
curl_easy_setopt(l_easy, CURLOPT_SSH_AUTH_TYPES, CURLSSH_AUTH_PASSWORD);
//curl_easy_setopt(l_easy, CURLOPT_PROTOCOLS, CURLPROTO_SFTP);
curl_easy_setopt(l_easy, CURLOPT_FOLLOWLOCATION, 1L);
curl_easy_setopt(l_easy, CURLOPT_CONNECTTIMEOUT, 20L);
curl_easy_setopt(l_easy, CURLOPT_LOW_SPEED_LIMIT, 1L);
curl_easy_setopt(l_easy, CURLOPT_LOW_SPEED_TIME, 30L);
curl_easy_setopt(l_easy, CURLOPT_TIMEOUT, 1510L);
curl_easy_setopt(l_easy, CURLOPT_BUFFERSIZE, 512000L);
// writing
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);
// logging
curl_easy_setopt(l_easy, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(
l_easy, CURLOPT_DEBUGFUNCTION, (curl_debug_callback)[](auto, auto
a_type, auto a_data, auto, auto a_client) {
return CURL_CLIENT(a_client)->logCallback(a_type, a_data);
});
curl_easy_setopt(l_easy, CURLOPT_DEBUGDATA, this);
// progress
curl_easy_setopt(
l_easy, CURLOPT_XFERINFOFUNCTION, (curl_xferinfo_callback)[](auto
a_client, auto a_total, auto a_now, auto, auto) {
return CURL_CLIENT(a_client)->progressCallback(a_total, a_now);
});
curl_easy_setopt(l_easy, CURLOPT_XFERINFODATA, this);
curl_easy_setopt(l_easy, CURLOPT_NOPROGRESS, 0L);
}
return l_easy;
}

This should come as no surprise but of course my first recommendation will be
to upgrade your libcurl to a recent release as whatever problem you experience
it is most likely addressed (or different) then.

I don't understand. The callback is your code. You make it return error!
