add_feed()
----------
::
feed_handle session::add_feed(feed_settings const& feed);
This adds an RSS feed to the session. The feed will be refreshed
regularly and optionally add all torrents from the feed, as they
appear. The feed is defined by the ``feed_settings`` object::
struct feed_settings
{
feed_settings();
std::string url;
bool auto_download;
int default_ttl;
add_torrent_params add_args;
};
By default ``auto_download`` is true, which means all torrents in
the feed will be downloaded. Set this to false in order to manually
add torrents to the session. You may react to the rss_alert_ when
a feed has been updated to poll it for the new items in the feed
when adding torrents manually. When torrents are added automatically,
you have to call ``session::get_torrents()`` to get the handles to
the new torrents.
Before adding the feed, you must set the ``url`` field to the
feed's url. It may point to an RSS or an atom feed.
The ``default_ttl`` is the default interval for refreshing a feed.
This may be overridden by the feed itself (by specifying the ``<ttl>``
tag) and defaults to 30 minutes. The field specifies the number of
minutes between refreshes.
If torrents are added automatically, you may want to set the
``add_args`` to appropriate values for download directory etc.
This object is used as a template for adding torrents from feeds,
but some torrent specific fields will be overridden by the
individual torrent being added. For more information on the
``add_torrent_params``, see `add_torrent()`_.
The returned feed_handle_ is a handle which is used to interact
with the feed, things like forcing a refresh or querying for
information about the items in the feed. For more information,
see feed_handle_.
remove_feed()
-------------
::
void session::remove_feed(feed_handle h);
Removes a feed from being watched by the session. When this
call returns, the feed handle is invalid and won't refer
to any feed.
get_feeds()
-----------
::
void session::get_feeds(std::vector<feed_handle>& f) const;

address of the interface it's going out over. This may be useful for multi-homed
clients with multiple interfaces to the internet.
feed_handle
===========
The ``feed_handle`` refers to a specific RSS feed which is watched by the session.
The ``feed_item`` struct is defined in ``<libtorrent/rss.hpp>``. It has the following
functions::
struct feed_handle
{
feed_handle();
void update_feed();
feed_status get_feed_status() const;
void set_settings(feed_settings const& s);
feed_settings settings() const;
};
update_feed()
-------------
::
void update_feed();
Forces an update/refresh of the feed. Regular updates of the feed is managed
by libtorrent, be careful to not call this too frequently since it may
overload the RSS server.
get_feed_status()
-----------------
::
feed_status get_feed_status() const;
Queries the RSS feed for information, including all the items in the feed.
The ``feed_status`` object has the following fields::
struct feed_status
{
std::string url;
std::string title;
std::string description;
time_t last_update;
int next_update;
bool updating;
std::vector<feed_item> items;
error_code error;
int ttl;
};
``url`` is the URL of the feed.
``title`` is the name of the feed (as specified by the feed itself). This
may be empty if we have not recevied a response from the RSS server yet,
or if the feed does not specify a title.
``description`` is the feed description (as specified by the feed itself).
This may be empty if we have not received a response from the RSS server
yet, or if the feed does not specify a description.
``last_update`` is the posix time of the last successful response from the feed.
``next_update`` is the number of seconds, from now, when the feed will be
updated again.
``updating`` is true if the feed is currently being updated (i.e. waiting for
DNS resolution, connecting to the server or waiting for the response to the
HTTP request, or receiving the response).
``items`` is a vector of all items that we have received from the feed. See
feed_item_ for more information.
``error`` is set to the appropriate error code if the feed encountered an
error.
``ttl`` is the current refresh time (in minutes). It's either the configured
default ttl, or the ttl specified by the feed.
set_settings() settings()
-------------------------
::
void set_settings(feed_settings const& s);
feed_settings settings() const;
Sets and gets settings for this feed. For more information on the
available settings, see `add_feed()`_.
feed_item
=========
The ``feed_item`` struct is defined in ``<libtorrent/rss.hpp>``.
::
struct feed_item
{
feed_item();
std::string url;
std::string uuid;
std::string title;
std::string description;
std::string comment;
std::string category;
size_type size;
torrent_handle handle;
sha1_hash info_hash;
};
``size`` is the total size of the content the torrent refers to, or -1
if no size was specified by the feed.
``handle`` is the handle to the torrent, if the session is already downloading
this torrent.
``info_hash`` is the info-hash of the torrent, or cleared (i.e. all zeroes) if
the feed does not specify the info-hash.
All the strings are self explanatory and may be empty if the feed does not specify
those fields.

rss_alert
---------
This alert is posted on RSS feed events such as start of RSS feed updates,
successful completed updates and errors during updates.
This alert is only posted if the ``rss_notifications`` category is enabled
in the alert mask.
::
struct rss_alert: alert
{
// ..
virtual std::string message() const;
enum state_t
{
state_updating, state_updated, state_error
};
feed_handle handle;
std::string url;
int state;
error_code error;
};
``handle`` is the handle to the feed which generated this alert.
``url`` is a short cut to access the url of the feed, without
having to call ``get_settings()``.
``state`` is one of:
``rss_alert::state_updating``
An update of this feed was just initiated, it will either succeed
or fail soon.
``rss_alert::state_updated``
The feed just completed a successful update, there may be new items
in it. If you're adding torrents manually, you may want to request
the feed status of the feed and look through the ``items`` vector.
``rss_akert::state_error``
An error just occurred. See the ``error`` field for information on
what went wrong.
``error`` is an error code used for when an error occurs on the feed.
