CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE(3) Library Functions Manual CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE(3)

CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - size threshold for pipelining penalty

#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE,
                            long size);

No function since pipelining was removed in 7.62.0.

Pass a long with a size in bytes. If a transfer in a pipeline is currently processing a request with a Content-Length larger than this CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE(3), that pipeline is not considered for additional requests, even if it is shorter than CURLMOPT_MAX_PIPELINE_LENGTH(3).

0, which means that the size penalization is inactive.

This functionality affects http only

int main(void)
{
  CURLM *m = curl_multi_init();
  long maxlength = 10000;
  curl_multi_setopt(m, CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE, maxlength);
}

Added in curl 7.30.0

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).
