CURLOPT_LOW_SPEED_LIMIT(3)

NAME
CURLOPT_LOW_SPEED_LIMIT - low speed limit in bytes per second

SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOW_SPEED_LIMIT,
                          long speedlimit);

DESCRIPTION
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.

DEFAULT
0, disabled

PROTOCOLS
This functionality affects all supported protocols

EXAMPLE
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    /* abort if slower than 30 bytes/sec during 60 seconds */
    curl_easy_setopt(curl, CURLOPT_LOW_SPEED_TIME, 60L);
    curl_easy_setopt(curl, CURLOPT_LOW_SPEED_LIMIT, 30L);
    res = curl_easy_perform(curl);
    if(CURLE_OPERATION_TIMEDOUT == res) {
      printf("Timeout.\n");
    }
    /* always cleanup */
    curl_easy_cleanup(curl);
  }
}

AVAILABILITY
Added in curl 7.1

RETURN VALUE
Returns CURLE_OK
