gnutls_session_ext_register — API function


#include <gnutls/gnutls.h>

int gnutls_session_ext_register(gnutls_session_t session, const char * name, int type, gnutls_ext_parse_type_t parse_type, 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, unsigned flags);


gnutls_session_t session
the session for which this extension will be set
const char * name
the name of the extension to register
int type
the numeric id of the extension
gnutls_ext_parse_type_t parse_type
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


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.

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().


GNUTLS_E_SUCCESS on success, otherwise a negative error code.
