NAME
TUI::Drivers::HardwareInfo::Win32 - Win32 hardware backend for Turbo Vision
DESCRIPTION
TUI::Drivers::HardwareInfo::Win32 provides the Windows-specific implementation of the THardwareInfo hardware interface used by the Turbo Vision driver layer.
The module encapsulates access to the Win32 console, keyboard, mouse, timer, and screen facilities. It maintains global process-level state and interfaces directly with the Windows Console API.
This module is not instantiated. All interaction is performed through class-level method calls.
Initialization of console resources is performed automatically when the module is loaded. Console state is restored automatically when the program terminates.
VARIABLES
The following variables are internal to the Win32 backend implementation and are not part of the portable THardwareInfo interface.
$insertState
Tracks the current insert mode state.
$platform
Contains the platform identifier string. For this backend, the value is Windows.
@consoleHandle
Holds the Win32 console handle objects used for input, output, and startup state.
$ownsConsole
Indicates whether the console was allocated by this module.
$consoleMode
Stores the console input mode.
$pendingEvent
Indicates whether a pending input event is buffered.
@irBuffer
Internal buffer for Win32 input records.
@crInfo
Stores console cursor information.
@sbInfo
Stores console screen buffer information.
IMPLEMENTATION
This module contains the Windows-specific implementation behind TUI::Drivers::HardwareInfo (THardwareInfo). Public API semantics and usage are documented in TUI::Drivers::HardwareInfo.
In this backend, those methods are mapped to Win32 console facilities for keyboard/mouse input, screen and caret control, timing, and control/error handling.
The exact implementation details here are platform-specific and may differ from other backends.
