パラメーター

名前	型	方向	説明
lpFileName	LPCWSTR	in	作成または開くファイルやデバイスの名前を指す文字列を指定する。
dwDesiredAccess	DWORD	in	要求するアクセス権を指定する。GENERIC_READやGENERIC_WRITE等のフラグ。
dwShareMode	DWORD	in	ファイルの共有モードを指定する。FILE_SHARE_READ等のフラグ。0で排他。
lpSecurityAttributes	SECURITY_ATTRIBUTES*	in	セキュリティ記述子と継承可否を持つSECURITY_ATTRIBUTES構造体へのポインタ。NULL可。
dwCreationDisposition	DWORD	in	存在有無に応じた動作を指定する。CREATE_NEWやOPEN_EXISTING等の値。
dwFlagsAndAttributes	DWORD	in	ファイル属性とフラグを指定する。FILE_ATTRIBUTE_NORMAL等の組み合わせ。
hTemplateFile	HANDLE	inoptional	属性を複製するテンプレートファイルのハンドルを指定する。通常NULL。
