|
|
.SH NAME
|
|
|
|
|
CURLOPT_MAX_RECV_SPEED_LARGE \- rate limit data download speed
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
.nf

|
|
|
|
#include <curl/curl.h>

|

|
2020-08-14 10:49:42 -04:00
|
|
|
curl_off_t maxspeed);
|
2014-06-19 11:59:00 -04:00
|
|
|
.SH DESCRIPTION
|
2020-08-14 10:49:42 -04:00
|
|
|
Pass a curl_off_t as parameter. If a download exceeds this \fImaxspeed\fP
|
2016-08-16 14:32:02 -04:00
|
|
|
(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.
|
2014-06-19 11:59:00 -04:00
|
|
|
|
2020-08-14 10:49:42 -04:00
|
|
|
This is not an exact science. libcurl attempts to keep the average speed below
|
|
|
|
|
the given threshold over a period time.
|
|
|
|
|
|
|
|
|
|
If you set \fImaxspeed\fP to a value lower than \fICURLOPT_BUFFERSIZE(3)\fP,
|
|
|
|
|
libcurl might download faster than the set limit initially.
|
|
|
|
|
|
2014-06-19 11:59:00 -04:00
|
|
|
This option doesn't affect transfer speeds done with FILE:// URLs.
