CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - Man Page
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 will not be 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.
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.
