CURLOPT_DNS_USE_GLOBAL_CACHE - enable/disable global DNS cache #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_USE_GLOBAL_CACHE, long enable); Pass a long. If the enable value is 1, it tells curl to use a global DNS cache that will survive between easy handle creations and deletions. This is not thread-safe and this will use a global variable. WARNING: this option is considered obsolete. Stop using it. Switch over to using the share interface instead! See CURLOPT_SHARE(3) and curl_share_init(3). 0 All
