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 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  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
       TODO

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.
