パラメーター

名前	型	方向	説明
distributionName	LPCWSTR	in	構成を取得する WSL ディストリビューション名(Unicode)。
distributionVersion	DWORD*	out	WSL のバージョン(1 または 2 等)を受け取るポインタ。
defaultUID	DWORD*	out	既定の Linux ユーザー ID を受け取るポインタ。
wslDistributionFlags	WSL_DISTRIBUTION_FLAGS*	out	現在のディストリビューションフラグを受け取るポインタ。
defaultEnvironmentVariables	LPSTR**	out	既定環境変数の文字列配列を受け取るポインタ。呼び出し側で解放が必要。
defaultEnvironmentVariableCount	DWORD*	out	返された環境変数の個数を受け取るポインタ。
