CURLMOPT_MAX_PIPELINE_LENGTH(3) Introduction to Library Functions

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 is used as the maximum amount of
outstanding requests in an HTTP/1.1 pipeline. This option is only
used for HTTP/1.1 pipelining, not for HTTP/2 multiplexing.

When this limit is reached, libcurl creates 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
CURLMOPT_MAX_PIPELINE_LENGTH(3).

DEFAULT

PROTOCOLS

This functionality affects all supported protocols

EXAMPLE

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

AVAILABILITY

Added in curl 7.30.0

RETURN VALUE
