/*
* 指定 Web ページのブックマーク登録者数を取得する
* written by H.Tsujimura 28 Jun 2006
*
* $Log: /comm/bookey/getUsers.c $
*
* 1 09/05/14 3:48 tsupo
* (1) ビルド環境のディレクトリ構造を整理
* (2) VSSサーバ拠点を変更
*
* 14 08/11/04 12:36 Tsujimura543
* getUsersOfNiftyClip() で 404 が返ってきた場合にも対応
*
* 13 08/11/04 12:25 Tsujimura543
* getUsersOfNiftyClip() を追加
*
* 12 07/09/05 1:48 Tsujimura543
* getUsersOfMMmemo() に第2引数を追加(stat1470netを引数化)
*
* 11 07/07/09 18:35 Tsujimura543
* getUsersOfDigg() を追加
*
* 10 07/03/01 21:40 Tsujimura543
* getUsersOfMMmemo() を改修、MM/Memo が応答しない場合は、以後、
* MM/Memo の API を呼び出さないようにした
*
* 9 07/03/01 21:38 Tsujimura543
* (1) getUsersOfDelicious() を改修(URLが長いとメモリ破壊が発生する不具合)
* (2) getUsersOfLivedoorClip() を追加
*
* 8 07/01/11 17:01 Tsujimura543
* 2007年1月10日付で「ECナビ人気ニュース」が Buzzurl に移行したのに
* 伴う修正
*
* 7 06/10/20 21:26 Tsujimura543
* 受信バッファオーバーラン対策を実施
*
* 6 06/10/11 17:47 Tsujimura543
* bookmark.getTotalCount (特定サイトの被はてなブックマーク数を取得する
* XML-RPC API)を使って、はてブ登録済みユーザ数を求めるようにしてみた
*
* 5 06/10/11 16:53 Tsujimura543
* はてブのエントリページのフォーマット変更により、ブックマーク登録者数が
* 取得できなくなってしまったため、新しいフォーマットに合わせて修正を実施
*
* 4 06/07/11 22:49 Tsujimura543
* ECナビ人気ニュースのブックマーク登録者数も表示するようにした
* (ブックマーク登録画面/EditBookmarkDialog)
*
* 3 06/07/03 14:19 Tsujimura543
* getUsersOfMMmemo() を修正 (MM/Memo のサーバから期待とは違う応答が
* 返ってきた場合に対応)
*
* 2 06/06/29 10:26 Tsujimura543
* バッファオーバーラン対策を実施
* (はてなブックマークのエントリページ取得処理)
*
* 1 06/06/28 15:54 Tsujimura543
* 新規作成 (動作確認済み)
