NAME
CURLOPT_DNS_USE_GLOBAL_CACHE - global DNS cache
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_USE_GLOBAL_CACHE,
long enable);
DESCRIPTION
Has no function since 7.62.0. Do not use!
Pass a long. If the enable value is 1, it tells curl to use a global
DNS cache that survives between easy handle creations and deletions.
This is not thread-safe and this uses a global variable.
See CURLOPT_SHARE(3) and curl_share_init(3) for the correct way to
share DNS cache between transfers.
DEFAULT
0
PROTOCOLS
All
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
CURLcode ret;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
/* switch off the use of a global, thread unsafe, cache */
curl_easy_setopt(curl, CURLOPT_DNS_USE_GLOBAL_CACHE, 0L);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITY
Deprecated since 7.11.1. Function removed in 7.62.0.

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
