CURLMOPT_PIPELINING(3) libcurl CURLMOPT_PIPELINING(3)
NAME
CURLMOPT_PIPELINING - enable HTTP pipelining and multiplexing
SYNOPSIS
#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING, long bitmask);
DESCRIPTION
Pass in the correct value in the bitmask parameter to instruct libcurl
to enable multiplexing for this multi handle.
With multiplexing enabled, libcurl attempts to do multiple transfers
over the same connection when doing parallel transfers to the same
hosts.
CURLPIPE_NOTHING
Default, which means doing no attempts at multiplexing.
CURLPIPE_HTTP1
This bit is deprecated and has no effect since version 7.62.0.
CURLPIPE_MULTIPLEX
If this bit is set, libcurl tries to multiplex the new transfer over
an existing connection if possible. This requires HTTP/2 or HTTP/3.
DEFAULT
Since 7.62.0, CURLPIPE_MULTIPLEX is enabled by default.
Before that, default was CURLPIPE_NOTHING.
PROTOCOLS
HTTP(S)
EXAMPLE
CURLM *m = curl_multi_init();
/* try HTTP/2 multiplexing */
curl_multi_setopt(m, CURLMOPT_PIPELINING, CURLPIPE_MULTIPLEX);
AVAILABILITY
Added in 7.16.0. Multiplex support bit added in 7.43.0. HTTP/1 Pipelin-
ing support was disabled in 7.62.0.
RETURN VALUE
Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION
if not.
