名前型方向説明
InfHandlevoid*in対象の開いているINFハンドル。
InfContextINFCONTEXT*inoptional対象行を示すINFCONTEXT構造体へのポインタ。NULLでFileNameを使う。
FileNameLPCSTRinoptionalサイズを求めるソースファイル名(ANSI)。InfContext指定時はNULL可。
SectionLPCSTRinoptionalファイルが属するコピーセクション名(ANSI)。NULL可。
FileSizeDWORD*out求めたファイルサイズを受け取る出力ポインタ。
RoundingFactorDWORDinサイズを切り上げる丸め単位(バイト)。0で丸めなし。
