# NAME

CURLOPT_MAX_RECV_SPEED_LARGE - rate limit data download speed
|

# SYNOPSIS
|
|
|
|
|
|
|
|
~~~c
|
|
|
|
#include <curl/curl.h>
|
|
|
|
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAX_RECV_SPEED_LARGE,
|
|
|
|
curl_off_t maxspeed);

# DESCRIPTION
|
|
|
|
|
|
|
|
Pass a curl_off_t as parameter. If a download exceeds this *maxspeed*
|
|
|
|
(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_BUFFERSIZE(3),
|
|
|
|
libcurl might download faster than the set limit initially.
|
|
|
|
|
|
|
|
This option does not affect transfer speeds done with FILE:// URLs.
