ARGUMENTS        top

       gnutls_session_t session                   is agnutls_session_ttype.       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

DESCRIPTION        top

       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 ofname depends on thetype type.  In case ofGNUTLS_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 ofname_length       zero it will clear all server names set.

RETURNS        top

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