.SH NAME
CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE \- chunk length threshold for pipelining
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE,
long size);
.fi
.SH DESCRIPTION
No function since pipelining was removed in 7.62.0.
Pass a long with a \fBsize\fP in bytes. If a transfer in a pipeline is
currently processing a chunked (Transfer\-encoding: chunked) request with a
current chunk length larger than \fICURLMOPT_CHUNK_LENGTH_PENALTY_SIZE(3)\fP,
that pipeline is not considered for additional requests, even if it is shorter
than \fICURLMOPT_MAX_PIPELINE_LENGTH(3)\fP.
.SH DEFAULT
0, which means that penalization is inactive.
.SH PROTOCOLS
This functionality affects http only
.SH EXAMPLE
.nf
int main(void)
{
CURLM *m = curl_multi_init();
long maxchunk = 10000;
curl_multi_setopt(m, CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE, maxchunk);
}
.fi
.SH AVAILABILITY
Added in curl 7.30.0
.SH RETURN VALUE
\fIcurl_multi_setopt(3)\fP returns a CURLMcode indicating success or error.
CURLM_OK (0) means everything was OK, non\-zero means an error occurred, see
\fIlibcurl\-errors(3)\fP.
