DisplayMode

構造体

サイズx64: 280 バイト / x86: 272 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド	型	サイズ	x64	x86	説明
DeviceName	WCHAR	64	+0	+0	対象ディスプレイデバイス名を表すワイド文字列。
devMode	DEVMODEW	216/208	+64	+64	ディスプレイ設定を保持するDEVMODEW構造体。解像度・色深度・周波数等を含む。
