23 .TH CURLOPT_SSL_FALSESTART 3 "14 Feb 2015" "libcurl 7.41.0" "curl_easy_setopt options"
24 .SH NAME
25 CURLOPT_SSL_FALSESTART \- enable TLS false start
26 .SH SYNOPSIS
27 #include <curl/curl.h>
28
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_FALSESTART, long enable);
30 .SH DESCRIPTION
31 Pass a long as parameter set to 1L to enable or 0 to disable.
32
33 This option determines whether libcurl should use false start during the TLS
34 handshake. False start is a mode where a TLS client will start sending
35 application data before verifying the server's Finished message, thus saving a
36 round trip when performing a full handshake.
37 .SH DEFAULT
38 0
39 .SH PROTOCOLS
40 All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
41 .SH EXAMPLE
42 .nf
43 CURL *curl = curl_easy_init();
44 if(curl) {
45 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
46 curl_easy_setopt(curl, CURLOPT_SSL_FALSESTART, 1L);
47 curl_easy_perform(curl);
48 }
49 .fi
50 .SH AVAILABILITY
51 Added in 7.42.0. This option is currently only supported by the NSS and
52 Secure Transport (on iOS 7.0 or later, or OS X 10.9 or later) TLS backends.
53 .SH RETURN VALUE
54 Returns CURLE_OK if false start is supported by the SSL backend, otherwise
55 returns CURLE_NOT_BUILT_IN.
