NAME

       CURLOPT_CONNECT_ONLY - stop when connected to target server

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECT_ONLY, long only);

DESCRIPTION

       Pass  a  long. If the parameter equals 1, it tells the library to perform all the required
       proxy authentication and connection setup, but no data transfer, and then return.

       The option can be used to simply test a connection to a server, but is  more  useful  when
       used  with  the CURLINFO_ACTIVESOCKET(3) option to curl_easy_getinfo(3) as the library can
       set up the connection and then the application can obtain the most  recently  used  socket
       for special data transfers.

DEFAULT

       0

PROTOCOLS

       HTTP, SMTP, POP3 and IMAP
