Virtual terminal processing2/13/2024 It also causes the contents of the console screen buffer to scroll up (./discarding the top row of the console screen buffer) when the cursor advances beyond the last row in the console screen buffer. This causes the rows displayed in the console window to scroll up automatically when the cursor advances beyond the last row in the window. When writing with WriteFile or WriteConsole or echoing with ReadFile or ReadConsole, the cursor moves to the beginning of the next row when it reaches the end of the current row. It should be enabled when using control sequences or when ENABLE_VIRTUAL_TERMINAL_PROCESSING is set. Backspace, tab, bell, carriage return, and line feed characters are processed. ValueĬharacters written by the WriteFile or WriteConsole function or echoed by the ReadFile or ReadConsole function are parsed for ASCII control sequences, and the correct action is performed. When a screen buffer is created, both output modes are enabled by default. If the hConsoleHandle parameter is a screen buffer handle, the mode can be one or more of the following values. The typical usage of this flag is intended in conjunction with ENABLE_VIRTUAL_TERMINAL_PROCESSING on the output handle to connect to an application that communicates exclusively via virtual terminal sequences. Setting this flag directs the Virtual Terminal processing engine to convert user input received by the console window into Console Virtual Terminal Sequences that can be retrieved by a supporting application through ReadFile or ReadConsole functions. Information about these events can be read from the input buffer by applications using the ReadConsoleInput function, but not by those using ReadFile or ReadConsole. User interactions that change the size of the console screen buffer are reported in the console's input buffer. To disable this mode, use ENABLE_EXTENDED_FLAGS without this flag. To enable this mode, use ENABLE_QUICK_EDIT_MODE | ENABLE_EXTENDED_FLAGS. ![]() This flag enables the user to use the mouse to select and edit text. If the ENABLE_LINE_INPUT mode is also enabled, backspace, carriage return, and line feed characters are handled by the system. If the input buffer is being read by ReadFile or ReadConsole, other control keys are processed by the system and are not returned in the ReadFile or ReadConsole buffer. The ReadConsoleInput function can be used to read MOUSE_EVENT input records from the input buffer.ĬTRL+C is processed by the system and is not placed in the input buffer. These events are discarded by ReadFile or ReadConsole, even when this mode is enabled. If the mouse pointer is within the borders of the console window and the window has the keyboard focus, mouse events generated by mouse movement and button presses are placed in the input buffer. If this mode is disabled, the functions return when one or more characters are available. ![]() The ReadFile or ReadConsole function returns only when a carriage return character is read. ![]() When disabled, all following text will be overwritten. When enabled, text entered in a console window will be inserted at the current cursor location and all text following that location will not be overwritten. This mode can be used only if the ENABLE_LINE_INPUT mode is also enabled. ValueĬharacters read by the ReadFile or ReadConsole function are written to the active screen buffer as they are typed into the console. When a console is created, all input modes except ENABLE_WINDOW_INPUT and ENABLE_VIRTUAL_TERMINAL_INPUT are enabled by default. If the hConsoleHandle parameter is an input handle, the mode can be one or more of the following values. For more information, see Console Buffer Security and Access Rights.Ī pointer to a variable that receives the current mode of the specified buffer. The handle must have the GENERIC_READ access right. ![]() Syntax BOOL WINAPI GetConsoleMode(Ī handle to the console input buffer or the console screen buffer. Retrieves the current input mode of a console's input buffer or the current output mode of a console screen buffer.
