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 will pause to keep the 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¶
EXAMPLE¶
CURL *curl = curl_easy_init(); if(curl) {
CURLcode ret;
curl_easy_setopt(curl, CURLOPT_URL, "");
/* 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¶
Added in 7.15.5
RETURN VALUE¶
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
