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

5

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

curl_multi_setopt(3) returns a CURLMcode indicating success or error.

CURLM_OK (0) means everything was OK, non−zero means an error occurred, see libcurl−errors(3).

SEE ALSO

CURLMOPT_MAX_HOST_CONNECTIONS(3), CURLMOPT_PIPELINING(3)
