CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE(3)                 Library Functions Manual

NAME
       CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - chunk length threshold for
       pipelining

SYNOPSIS
       #include <curl/curl.h>

       CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE,
                                   long size);

DESCRIPTION
       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).

DEFAULT
       0, which means that penalization is inactive.

PROTOCOLS
       This functionality affects http only

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

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).
