1470 - # (human-readable) website whose feed you want to poll, or NULL.
1471 - #
1472 - # If $uri is NULL, then FeedWordPress will poll any feeds that are
1473 - # ready for polling. It will not poll feeds that are marked as
1474 - # "Invisible" Links (signifying that the subscription has been
1475 - # de-activated), or feeds that are not yet stale according to their
1476 - # TTL setting (which is either set in the feed, or else set
1477 - # randomly within a window of 30 minutes - 2 hours).
1478 - #
1479 - # Returns:
1480 - # --------
1481 - # * Normally returns an associative array, with 'new' => the number
1482 - # of new posts added during the update, and 'updated' => the number
1483 - # of old posts that were updated during the update. If both numbers
1484 - # are zero, there was no change since the last poll on that URI.
1485 - #
1486 - # * Returns NULL if URI it was passed was not a URI that this
1487 - # installation of FeedWordPress syndicates.
1488 - #
1489 - # Effects:
1490 - # --------
1491 - # * One or more feeds are polled for updates
1492 - #
1493 - # * If the feed Link does not have a hardcoded name set, its Link
1494 - # Name is synchronized with the feed's title element
1495 - #
1496 - # * If the feed Link does not have a hardcoded URI set, its Link URI
1497 - # is synchronized with the feed's human-readable link element
1498 - #
1499 - # * If the feed Link does not have a hardcoded description set, its
1500 - # Link Description is synchronized with the feed's description,
1501 - # tagline, or subtitle element.
1502 - #
1503 - # * The time of polling is recorded in the feed's settings, and the
1504 - # TTL (time until the feed is next available for polling) is set
1505 - # either from the feed (if it is supplied in the ttl or syndication
1506 - # module elements) or else from a randomly-generated time window
1507 - # (between 30 minutes and 2 hours).
1508 - #

1512 - # WordPress store.

1718 + * use the title provided in $name and the homepage URL in $uri
1719 + *

1722 + * @param string $rss The URI for the feed itself (for example, <http://radgeek.com/feed/>)
