gnutls_handshake - API function
int gnutls_handshake(gnutls_session_t session);
is a gnutls_session_t structure.
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 resumed later.
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 or in the case of GNUTLS_E_GOT_APPLICATION_DATA it might also mean that some data were pending.
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
