.Sh 解説
|
|
.Fn DEV_MODULE
|
|
マクロはデバイスドライバカーネルモジュールを宣言します。
|
|
これは
|
|
.Vt moduledata_t
|
|
構造体を埋めて、それから
|
|
.Fn DECLARE_MODULE
|
|
を正しい引数で呼び出します。ここで、
|
|
.Fa name
|
|
はモジュール名で、
|
|
.Fa ( arg
|
|
を引数として持つ)
|
|
.Fa evh
|
|
はそのモジュールのためのイベントハンドラです (詳細については
|
|
.Xr DECLARE_MODULE 9
|
|
を参照)。
|
|
イベントハンドラはロード時に
|
|
.Fn make_dev
|
|
でデバイスを作成し、アンロードされる時に
|
|
.Fn destroy_dev
|
|
でそのデバイスを破壊することを、期待されています。
|
|
