.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.
|
|
|
|
The option can be used to simply test a connection to a server, but is more
|
|
useful when used with the \fICURLINFO_ACTIVESOCKET(3)\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.
|
|
.SH DEFAULT
|
|
0
|
|
.SH PROTOCOLS

|
HTTP, SMTP, POP3 and IMAP
