gnutls_ext_register - API function
#include <gnutls/gnutls.h>
int gnutls_ext_register(const char * name, int id,
gnutls_ext_parse_type_t parse_point, gnutls_ext_recv_func
recv_func, gnutls_ext_send_func send_func,
gnutls_ext_deinit_data_func deinit_func, gnutls_ext_pack_func
pack_func, gnutls_ext_unpack_func unpack_func);
const char * name
the name of the extension to register
int id the numeric TLS 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
This function will register a new extension type. The extension
will remain registered until gnutls_global_deinit() is called. If
the extension type is already registered then
GNUTLS_E_ALREADY_REGISTERED will be returned.
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().
Any extensions registered with this function are valid for the
client and TLS1.2 server hello (or encrypted extensions for
TLS1.3).
This function is not thread safe.
GNUTLS_E_SUCCESS on success, otherwise a negative error code.
3.4.0
