# NAME
|
|
|
|
CURLMOPT_PIPELINING - enable HTTP multiplexing
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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 (0)
|
|
|
|
Default, which means doing no attempts at multiplexing.
|
|
|
|
## CURLPIPE_HTTP1 (1)
|
|
|
|
This bit is deprecated and has no effect since version 7.62.0.
|
|
|
|
## CURLPIPE_MULTIPLEX (2)
|
|
|
|
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**.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
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 Pipelining
|
|
support was disabled in 7.62.0.
|
|
|
|
# RETURN VALUE
|
|
|
|
Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not.
