加速度センサー友の会コミュのThinkPadでの使い方

プログラム中で以下のようにしてアクセスできます。
ShockData構造体は別途定義する必要あります。
----------------------------
HANDLE hFile;
hFile = CreateFile("\\\\.\\ShockMgr", GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
unsigned long ulRead = 0;
ShockData sd;
DeviceIoControl( hFile, 0x733fc, NULL, 0, (void *)&sd, 0x24, &ulRead, NULL);

sd.y0; // 横方向の加速度
sd.x0; // 前後方向の加速度
----------------------------
