gnutls_server_name_set3

Api function

Usage

#include <gnutls/gnutls.h>

int gnutls_server_name_set(gnutls_session_t session, gnutls_server_name_type_t type, const void * name, size_t name_length);

Arguments

gnutls_session_t session

is a gnutls_session_t type.

gnutls_server_name_type_t type

specifies the indicator type

const void * name

is a string that contains the server name.

size_t name_length

holds the length of name excluding the terminating null byte

Overview

This function is to be used by clients that want to inform (via a TLS extension mechanism) the server of the name they connected to. This should be used by clients that connect to servers that do virtual hosting.

The value of name depends on the type type. In case of GNUTLS_NAME_DNS, a UTF-8 null-terminated domain name string, without the trailing dot, is expected.

IPv4 or IPv6 addresses are not permitted to be set by this function. If the function is called with a name of name_length zero it will clear all server names set.

Returns

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned.
