1863 - # (human-readable) website whose feed you want to poll, or NULL.
1864 - #
1865 - # If $uri is NULL, then FeedWordPress will poll any feeds that are
1866 - # ready for polling. It will not poll feeds that are marked as
1867 - # "Invisible" Links (signifying that the subscription has been
1868 - # de-activated), or feeds that are not yet stale according to their
1869 - # TTL setting (which is either set in the feed, or else set
1870 - # randomly within a window of 30 minutes - 2 hours).
1871 - #
1872 - # Returns:
1873 - # --------
1874 - # * Normally returns an associative array, with 'new' => the number
1875 - # of new posts added during the update, and 'updated' => the number
1876 - # of old posts that were updated during the update. If both numbers
1877 - # are zero, there was no change since the last poll on that URI.
1878 - #
1879 - # * Returns NULL if URI it was passed was not a URI that this
1880 - # installation of FeedWordPress syndicates.
1881 - #
1882 - # Effects:
1883 - # --------
1884 - # * One or more feeds are polled for updates
1885 - #
1886 - # * If the feed Link does not have a hardcoded name set, its Link
1887 - # Name is synchronized with the feed's title element
1888 - #
1889 - # * If the feed Link does not have a hardcoded URI set, its Link URI
1890 - # is synchronized with the feed's human-readable link element
1891 - #
1892 - # * If the feed Link does not have a hardcoded description set, its
1893 - # Link Description is synchronized with the feed's description,
1894 - # tagline, or subtitle element.
1895 - #
1896 - # * The time of polling is recorded in the feed's settings, and the
1897 - # TTL (time until the feed is next available for polling) is set
1898 - # either from the feed (if it is supplied in the ttl or syndication
1899 - # module elements) or else from a randomly-generated time window
1900 - # (between 30 minutes and 2 hours).
1901 - #
1902 - # * New posts from the polled feed are added to the WordPress store.
