eve.core.windows.signals

Signal handling support for the Windows event loop.

This module manages console control signal detection and dispatch for the Windows event loop. Windows signals are delivered via SetConsoleCtrlHandler on a separate thread and must be bridged to the event loop through atomic flags and IOCP wakeup.

structSignalState

Manages console control signal state and detection.

Windows delivers CTRL_C, CTRL_BREAK, and CTRL_CLOSE events on a separate thread. This struct bridges those events to the event loop using atomic flags that are checked each iteration.

Fields

bool consoleHandlerInstalled

Methods

void install(SelectedBackend * poller) @trusted nothrowInstall the console control handler.

void checkEvents(Slot, DispatchFn)(scope Slot[] slots, scope DispatchFn dispatchFn) @trusted nothrowCheck for pending console control signals and dispatch them.

bool isInstalled() const @safe nothrow @nogcCheck whether the console control handler has been installed.
