CURLOPT_LOW_SPEED_LIMIT - set low speed limit in bytes per second #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOW_SPEED_LIMIT, long speedlimit); Pass a long as parameter. It contains the average transfer speed in bytes per second that the transfer should be below during CURLOPT_LOW_SPEED_TIME(3) seconds for libcurl to consider it to be too slow and abort. 0, disabled All

curl = curl_easy_init();
if(curl) {
 curl_easy_setopt(curl, CURLOPT_URL, url);
 /* abort if slower than 30 bytes/sec during 60 seconds */
 curl_easy_setopt(curl, CURLOPT_LOW_SPEED_TIME, 60L);

Always Returns CURLE_OK CURLOPT_LOW_SPEED_TIME "(3), " CURLOPT_TIMEOUT "(3), "
