Аргументы (Arguments)
gnutls_session_t session
the session for which this extension will be set
const char * name
the name of the extension to register
int id the numeric id of the extension
gnutls_ext_parse_type_t parse_point
the parse type of the extension (see
gnutls_ext_parse_type_t)
gnutls_ext_recv_func recv_func
a function to receive the data
gnutls_ext_send_func send_func
a function to send the data
gnutls_ext_deinit_data_func deinit_func
a function deinitialize any private data
gnutls_ext_pack_func pack_func
a function which serializes the extension's private
data (used on session packing for resumption)
gnutls_ext_unpack_func unpack_func
a function which will deserialize the extension's
private data
unsigned flags
must be zero or flags from gnutls_ext_flags_t
Описание (Description)
This function will register a new extension type. The extension
will be only usable within the registered session. If the
extension type is already registered then
GNUTLS_E_ALREADY_REGISTERED
will be returned, unless the flag
GNUTLS_EXT_FLAG_OVERRIDE_INTERNAL
is specified. The latter flag
when specified can be used to override certain extensions
introduced after 3.6.0. It is expected to be used by applications
which handle custom extensions that are not currently supported
in GnuTLS, but direct support for them may be added in the
future.
Each registered extension can store temporary data into the
gnutls_session_t structure using gnutls_ext_set_data()
, and they
can be retrieved using gnutls_ext_get_data()
.
The validity of the extension registered can be given by the
appropriate flags of gnutls_ext_flags_t
. If no validity is given,
then the registered extension will be valid for client and TLS1.2
server hello (or encrypted extensions for TLS1.3).
Возвращаемое значение (Return value)
GNUTLS_E_SUCCESS
on success, otherwise a negative error code.
