Ok for curl_multi_info_read. I changed my code as follow :
curlret = curl_multi_perform(m_pstCurlMultiHandle, &iRunningFDs);
if (!iRunningFDs)
{
usleep(10000);
}
else
{
if(curlret == CURLM_OK) {
int iWaitFDs = 0;
/* wait for activity, timeout or "nothing" */
curlret = curl_multi_wait(m_pstCurlMultiHandle, NULL, 0, 10000,
&iWaitFDs);
if (iWaitFDs)
{
struct CURLMsg *m;
do {
int msgq = 0;
m = curl_multi_info_read(m_pstCurlMultiHandle, &msgq);
if(m && (m->msg == CURLMSG_DONE)) {
//Find the connection using this handle
if (m->data.result != CURLE_OK)
{
for (int i = 0; i < MAX_CONNECTIONS; i++)
{
if (m->easy_handle == m_plstCURLHandles[i]->m_pstHandle)
{
CHSSConnection * poConnection = m_plstConnectionList[i];
//Discard all buffers and put session back in PREINIT
poConnection->resetConnection();
//Remove curl handle from multihandle
curl_multi_remove_handle(m_pstCurlMultiHandle,
m->easy_handle);
}
}
}
}
} while(m);
}
}
}
However this does not work, as multi_wait will here "wait" for the
duration. I dont want this behaviour because the data to be sent are coming
from another thread and i want to send them as soon as they are available.
Maybe i should add a specific file descriptor in the multi_wait that would
trigger it ? Seems like quite complicated
