# NAME
|
||
|
|
|
||
|
|
CURLOPT_MAX_SEND_SPEED_LARGE - rate limit data upload speed
|
||
|
|

|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.
