Reboot
Reboot (Ver.1.21) is a Workbench Tools menu utility that provides a safe, user-confirmed system reboot. It installs itself as an AppMenuItem in the Workbench Tools menu and, when selected, displays an AsmRequest dialog (with an optional image and sound) asking the user to confirm the reboot.
Features
- AppMenuItem integration — Adds a “Reboot” entry to the Workbench Tools menu
- AsmRequest dialog — Confirmation dialog with DataType image and optional sound
- Localization — All strings loaded from a locale catalog (
Reboot.catalog) - ToolType configuration — IMAGE, SOUND, APPMENUNAME, RETURNKEY, TEXTUNDEROBJ
- Safe reboot — Only reboots on AmigaOS 3.0+ (Exec V39+) using
ColdReboot()

;How It Works
-
ToolType configuration — On startup,
GetDefToolsTypes()reads the program icon’s ToolTypes for IMAGE (dialog image file), SOUND (optional sound effect), APPMENUNAME (menu entry text), RETURNKEY (whether Return key confirms), and TEXTUNDEROBJ (text position relative to image). -
DataType loading —
LoadNewDTObject()loads a BSH (brush) image and optionally a sound DataType object for the confirmation dialog. -
AsmRequest setup —
AllocAsmRequest()creates a reusable requester with the image, sound, centering, and justification options. -
AppMenuItem —
AddAppMenuItemA()installs an entry in the Workbench Tools menu. The program then enters aWaitPort()loop, waiting for the user to select it. -
Confirmation — When the menu item is selected,
AsmRequestArgs()displays the dialog with three options: Reboot, Quit, or Cancel. -
Reboot — If confirmed and running on AmigaOS 3.0+, calls
Disable()followed byColdReboot()to perform a clean system restart.
The ColdReboot() call is a hardware-level reset. The Disable() call before it prevents interrupts from interfering with the reboot sequence. The version check (ExecBase->lib_Version >= 39) ensures this only runs on AmigaOS 3.0 or later where ColdReboot() is available.
