There are no additional data members in this alert.
Typically, when receiving this alert, you would want to save the torrent file in order
to load it back up again when the session is restarted. Here's an example snippet of
code to do that::
torrent_handle h = alert->handle();
if (h.is_valid()) {
torrent_info const& ti = h.get_torrent_info();
create_torrent ct(ti);
entry te = ct.generate();
std::vector<char> buffer;
bencode(std::back_inserter(buffer), te);
FILE* f = fopen((to_hex(ti.info_hash().to_string()) + ".torrent").c_str(), "w+");
if (f) {
fwrite(&buffer[0], 1, buffer.size(), f);
fclose(f);
}
}
