NAME
gnutls_handshake - This is the main function in the handshake protocol.
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_handshake(gnutls_session_t session);
ARGUMENTS
gnutls_session_t session
is a gnutls_session_t structure.
DESCRIPTION
This function does the handshake of the TLS/SSL protocol, and
initializes the TLS connection.
This function will fail if any problem is encountered, and will return
a negative error code. In case of a client, if the client has asked to
resume a session, but the server couldn’t, then a full handshake will
be performed.
The non-fatal errors such as GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED
interrupt the handshake procedure, which should be later be resumed.
Call this function again, until it returns 0; cf.
gnutls_record_get_direction() and gnutls_error_is_fatal().
If this function is called by a server after a rehandshake request then
GNUTLS_E_GOT_APPLICATION_DATA or GNUTLS_E_WARNING_ALERT_RECEIVED may be
returned. Note that these are non fatal errors, only in the specific
case of a rehandshake. Their meaning is that the client rejected the
rehandshake request.
RETURNS
GNUTLS_E_SUCCESS on success, otherwise an error.
