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

#include <curl/curl.h>

|
|
|
curl_off_t maxspeed);
|
2014-06-19 23:59:00 +08:00
|
|
|
.SH DESCRIPTION
|
2020-08-14 22:49:42 +08:00
|
|
|
Pass a curl_off_t as parameter. If a download exceeds this \fImaxspeed\fP
|
2016-08-17 02:32:02 +08:00
|
|
|
(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 23:59:00 +08:00
|
|
|
|
2020-08-14 22:49:42 +08:00
|
|
|
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.
|
|
|
|
|
|
2021-10-31 23:34:44 +08:00
|
|
|
This option does not affect transfer speeds done with FILE:// URLs.
