gnutls_server_name_set — API function


#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);


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


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.


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