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
