NAME

       CURLMOPT_MAX_PIPELINE_LENGTH - maximum number of requests in a pipeline

SYNOPSIS

       #include <curl/curl.h>

       CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_MAX_PIPELINE_LENGTH,
                                   long max);

DESCRIPTION

       No function since pipelining was removed in 7.62.0.

       Pass a long. The set max number will be used as the maximum amount of outstanding requests in an HTTP/1.1
       pipelined connection. This option is only used for HTTP/1.1 pipelining, not for HTTP/2 multiplexing.

       When   this   limit   is   reached,   libcurl   will  use  another  connection  to  the  same  host  (see
       CURLMOPT_MAX_HOST_CONNECTIONS(3)), or queue the request until one of the pipelines to the host  is  ready
       to  accept a request.  Thus, the total number of requests in-flight is CURLMOPT_MAX_HOST_CONNECTIONS(3) *
       CURLMOPT_MAX_PIPELINE_LENGTH(3).

DEFAULT

       5

PROTOCOLS

       HTTP(S)

EXAMPLE

       CURLM *m = curl_multi_init();
       /* set a more conservative pipe length */
       curl_multi_setopt(m, CURLMOPT_MAX_PIPELINE_LENGTH, 3L);

AVAILABILITY

       Added in 7.30.0

RETURN VALUE

       Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not.
