はじめに
Yosemite環境で住基カードを読み込ませた際に、以下のエラーになります。
SCardStatus NG
returns SCARD_E_INSUFFICIENT_BUFFERU(0x80100008)
Yosemiteのバグ
以下のページによるとYosemiteのバグのようです。
SCardStatus() does not correctly report the reader name length. The terminating NUL character of the reader name is not counted. So a second call to SCardStatus() using the size returned by the first SCardStatus() call will fail with 0x80100008 (that is SCARD_E_INSUFFICIENT_BUFFER).
It is a really stupid bug and very easy to fix for Apple.
