CURLOPT_MAX_SEND_SPEED_LARGE(3)                       Library Functions Manual

NAME
       CURLOPT_MAX_SEND_SPEED_LARGE - rate limit data upload speed

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAX_SEND_SPEED_LARGE,
                                 curl_off_t maxspeed);

DESCRIPTION
       Pass a curl_off_t as parameter with the maxspeed. If an upload exceeds
       this speed (counted in bytes per second) the transfer pauses to keep
       the average speed less than or equal to the parameter value. Defaults
       to unlimited speed.

       This is not an exact science. libcurl attempts to keep the average
       speed below the given threshold over a period time.

       If you set maxspeed to a value lower than CURLOPT_UPLOAD_BUFFERSIZE(3),
       libcurl might "shoot over" the limit on its first send and still send
       off a full buffer.

       This option does not affect transfer speeds done with FILE:// URLs.

DEFAULT
       0, disabled

PROTOCOLS
       All

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode ret;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           /* cap the upload speed to 1000 bytes/sec */
           curl_easy_setopt(curl, CURLOPT_MAX_SEND_SPEED_LARGE, (curl_off_t)1000);
           /* (set some upload options as well!) */
           ret = curl_easy_perform(curl);
         }
       }

AVAILABILITY
