パラメーター

名前	型	方向	説明
lpszAppFilename	LPCWSTR	in	優先度を問い合わせるアプリの実行ファイル名(Unicode)へのポインタ。
dwMediaMode	DWORD	in	対象とするメディアモードを示すフラグ(LINEMEDIAMODE_*)。
lpExtensionID	LINEEXTENSIONID*	inout	拡張機能を識別するLINEEXTENSIONIDへのポインタ。不要ならNULL。
dwRequestMode	DWORD	in	要求の種類を示すフラグ(LINEREQUESTMODE_*)。
lpExtensionName	VARSTRING*	inout	拡張名を受け取るVARSTRINGへのポインタ。
lpdwPriority	DWORD*	inout	取得した優先度を受け取る出力ポインタ。1で優先、0で非優先。
