<p class="level0"><a name="NAME"></a><h2 class="nroffsh">NAME</h2>
<p class="level0">CURLMOPT_PIPELINING - enable/disable HTTP pipelining <a name="SYNOPSIS"></a><h2 class="nroffsh">SYNOPSIS</h2>
<p class="level0">#include <curl/curl.h>
<p class="level0">CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING, long bits); <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">Set the <span Class="bold">bits</span> parameter to 1 to make libcurl use HTTP pipelining for HTTP/1.1 transfers done using this multi handle, as far as possible. This means that if you add a second request that can use an already existing connection, the second request will be "piped" on the same connection rather than being executed in parallel.
<p class="level0">When using pipelining, there are also several other related options that are interesting to tweak and adjust to alter how libcurl spreads out requests on different connections or not etc.
<p class="level0">Starting in 7.43.0, the <span Class="bold">bits</span> parameter's bit 1 also has a meaning and libcurl is now offering symbol names for the bits:
<p class="level0"><a name="CURLPIPENOTHING"></a><span class="nroffip">CURLPIPE_NOTHING (0)</span>
<p class="level1">Default, which means doing no attempts at pipelining or multiplexing.
<p class="level0"><a name="CURLPIPEHTTP1"></a><span class="nroffip">CURLPIPE_HTTP1 (1)</span>
<p class="level1">If this bit is set, libcurl will try to pipeline HTTP/1.1 requests on connections that are already established and in use to hosts.
<p class="level0"><a name="CURLPIPEMULTIPLEX"></a><span class="nroffip">CURLPIPE_MULTIPLEX (2)</span>
<p class="level1">If this bit is set, libcurl will try to multiplex the new transfer over an existing connection if possible. This requires HTTP/2. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
<p class="level0">0 (off) <a name="PROTOCOLS"></a><h2 class="nroffsh">PROTOCOLS</h2>
<p class="level0">HTTP(S) <a name="EXAMPLE"></a><h2 class="nroffsh">EXAMPLE</h2>

<p class="level0">Added in 7.16.0. Multiplex support bit added in 7.43.0. <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
<p class="level0">Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not. <a name="SEE"></a><h2 class="nroffsh">SEE ALSO</h2>
