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);
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.
