27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECT_ONLY, long only);
31 Pass a long. If the parameter equals 1, it tells the library to perform all
32 the required proxy authentication and connection setup, but no data transfer,
35 The option can be used to simply test a connection to a server, but is more
36 useful when used with the \fICURLINFO_ACTIVESOCKET(3)\fP option to
37 \fIcurl_easy_getinfo(3)\fP as the library can set up the connection and then
38 the application can obtain the most recently used socket for special data
43 HTTP, SMTP, POP3 and IMAP
49 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
