| .TH CURLMOPT_PIPELINING 3 "17 Jun 2014" "libcurl 7.37.0" "curl_multi_setopt options" |
| .SH NAME |
| CURLMOPT_PIPELINING \- enable/disable HTTP pipelining |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING, long bits); |
| .SH DESCRIPTION |
| Set the \fBbits\fP 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. |
| |
| 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. |
| |
| Starting in 7.43.0, the \fBbits\fP parameter's bit 1 also has a meaning and |
| libcurl is now offering symbol names for the bits: |
| .IP CURLPIPE_NOTHING (0) |
| Default, which means doing no attempts at pipelining or multiplexing. |
| .IP CURLPIPE_HTTP1 (1) |
| 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. |
| .IP CURLPIPE_MULTIPLEX (2) |
| If this bit is set, libcurl will try to multiplex the new transfer over an |
| existing connection if possible. This requires HTTP/2. |
| .SH DEFAULT |
| 0 (off) |
| .SH PROTOCOLS |
| HTTP(S) |
| .SH EXAMPLE |
| TODO |
| .SH AVAILABILITY |
| Added in 7.16.0. Multiplex support bit added in 7.43.0. |
| .SH RETURN VALUE |
| Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not. |
