#include <curl/curl.h>
CURLSH *curl_share_init( );

This share handle is what you pass to curl using the CURLOPT_SHARE option with curl_easy_setopt(3), to make that specific curl handle use the data in this share.
If this function returns NULL, something D it took from the start until the name resolving was completed.
CURLINFO_CONNECT_TIME. The time it took from the start until the connect to the remote host (or proxy) was completed.
