gnutls_session_set_finished_function(3)

Usage

#include <gnutls/gnutls.h>

void gnutls_session_set_finished_function(gnutls_session_t session, gnutls_finished_callback_func func);

Arguments

`gnutls_session_t session`	is a `gnutls_session_t` structure.
`gnutls_finished_callback_func func`	a `gnutls_finished_callback_func` callback.

Overview

Register a callback function for the session that will be called when a TLS Finished message has been generated. The function is typically used to copy away the TLS finished message for later use as a channel binding or similar purpose.

The callback should follow this prototype

void callback (gnutls_session_t session, const void *finished, size_t len);

The finished parameter will contain the binary TLS finished message, and len will contains its length. For SSLv3 connections, the len parameter will be 36 and for TLS connections it will be 12.

It is recommended that the function returns quickly in order to not delay the handshake. Use the function to store a copy of the TLS finished message for later use.
