CURLMOPT_MAX_PIPELINE_LENGTH(3)

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
All

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 7.30.0

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