.TH CURLOPT_SSL_FALSESTART 3 "14 Feb 2015" "libcurl 7.41.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_SSL_FALSESTART \- enable TLS false start
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_FALSESTART, long enable);
.SH DESCRIPTION
Pass a long as parameter set to 1 to enable or 0 to disable.
This option determines whether libcurl should use false start during the TLS
handshake. False start is a mode where a TLS client will start sending
application data before verifying the server's Finished message, thus saving a
round trip when performing a full handshake.
.SH DEFAULT
0
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
.SH EXAMPLE
TODO
.SH AVAILABILITY
Added in 7.42.0. This option is currently only supported by the NSS and
Secure Transport (on iOS 7.0 or later, or OS X 10.9 or later) TLS backends.
.SH RETURN VALUE
Returns CURLE_OK if false start is supported by the SSL backend, otherwise
returns CURLE_NOT_BUILT_IN.
