gnutls_ext_register(3) gnutls gnutls_ext_register(3) NAME gnutls_ext_register - API function SYNOPSIS #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); ARGUMENTS 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 DESCRIPTION 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_ses- sion_t structure using gnutls_ext_set_data(), and they can be retrieved us- ing 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. RETURNS GNUTLS_E_SUCCESS on success, otherwise a negative error code. SINCE 3.4.0 REPORTING BUGS Report bugs to <bugs@gnutls.org>.
