CURLMOPT_MAX_PIPELINE_LENGTH(3)                      curl_multi_setopt options

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.
