CURLMOPT_PIPELINING_SITE_BL(3)

CURLMOPT_PIPELINING_SITE_BL3

Pipelining host block list

Usage

#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING_SITE_BL,
                            char **hosts);

Overview

No function since pipelining was removed in 7.62.0.

Pass a hosts array of char *, ending with a NULL entry. This is a list of sites that are blocked from pipelining, i.e sites that are known to not support HTTP pipelining. The array is copied by libcurl.

Pass a NULL pointer to clear the block list.

Default

NULL, which means that there is no block list.

Protocols

This functionality affects http only

Examples

static const char *site_block_list[] =
{
  "www.haxx.se",
  "www.example.com:1234",
  NULL
};
int main(void)
{
  CURLM *m = curl_multi_init();
  curl_multi_setopt(m, CURLMOPT_PIPELINING_SITE_BL, site_block_list);
}

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).
