.TH CURLOPT_CONNECT_ONLY 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_CONNECT_ONLY \- stop when connected to target server
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECT_ONLY, long only);
.SH 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.
2014-06-19 13:53:13 +02:00
The option can be used to simply test a connection to a server, but is more
useful when used with the \fICURLINFO_LASTSOCKET\fP option to
\fIcurl_easy_getinfo(3)\fP as the library can set up the connection and then
the application can obtain the most recently used socket for special data
transfers.
