| 名前 | 型 | 方向 | 説明 |
|---|---|---|---|
| dnDevInst | DWORD | in | プロパティを取得する対象デバイスインスタンス(DEVINST)を指定する。 |
| PropertyKey | DEVPROPKEY* | in | 取得する統合デバイスプロパティのキー(DEVPROPKEY)へのポインターを指定する。 |
| PropertyType | DEVPROPTYPE* | out | 取得した値のデータ型(DEVPROPTYPE)を受け取るポインター。 |
| PropertyBuffer | BYTE* | outoptional | プロパティ値を受け取るバッファーへのポインター。サイズ問い合わせ時はNULL可。 |
| PropertyBufferSize | DWORD* | inout | 入力時はバッファーサイズ、出力時は必要サイズ(バイト)を示すDWORDへのポインター。 |
| ulFlags | DWORD | in | 動作を制御するフラグ。通常は0を指定する。 |
| hMachine | INT_PTR | inoptional | 対象マシンへの接続ハンドルを指定する。ローカルの場合はNULL(0)を指定する。 |
