CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - chunk length threshold for pipelining

#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_CHUNK_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 chunked (Transfer-encoding: chunked) request with a current chunk length larger than CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE(3), that pipeline is not considered for additional requests, even if it is shorter than CURLMOPT_MAX_PIPELINE_LENGTH(3).

The default value is 0, which means that the penalization is inactive.

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

Added in 7.30.0

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