CURLOPT_SSL_FALSESTART(3)  curl_easy_setopt options  CURLOPT_SSL_FALSESTART(3)

NAME
       CURLOPT_SSL_FALSESTART -	enable TLS false start

SYNOPSIS
       #include	<curl/curl.h>

       CURLcode	 curl_easy_setopt(CURL	*handle,  CURLOPT_SSL_FALSESTART, long
       enable);

DESCRIPTION
       Pass a long as parameter	set to 1L 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  mes-
       sage, thus saving a round trip when performing a	full handshake.

DEFAULT
       0

PROTOCOLS
       All TLS based protocols:	HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl)	{
	 curl_easy_setopt(curl,	CURLOPT_URL, "https://example.com");
	 curl_easy_setopt(curl,	CURLOPT_SSL_FALSESTART,	1L);
	 curl_easy_perform(curl);
       }

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 back-
       ends.

RETURN VALUE
       Returns CURLE_OK	if false start is supported by the SSL backend,	other-
       wise returns CURLE_NOT_BUILT_IN.
