How to respond to Orchestrated C++ Console App Termination

[Lindsay-Mathieson]

I have a C++ console project as part of a Aspire project, including in the run. Have setup SetConsoleCtrlHandler, atExit and signal handler for cleanup on close, they work fine when running from the command line.

However, when running under Aspire and closing the Aspire console it seems to hard kill my console app, none of the standard closing handlers are invoked.

HANDLE closeEvent = CreateEvent(NULL, TRUE, FALSE, NULL);

BOOL WINAPI consoleHandler(DWORD signal) {

	PLOGI << "consoleHandlerInvoked"; // do cleanup
	switch (signal)
	{
	case CTRL_C_EVENT:
		PLOGI << "CTRL_C_EVENT"; break;

	case CTRL_BREAK_EVENT:
		PLOGI << "CTRL_BREAK_EVENT"; break;

	case CTRL_CLOSE_EVENT:
		PLOGI << "CTRL_CLOSE_EVENT"; 	break;

	case CTRL_LOGOFF_EVENT:
		PLOGI << "CTRL_LOGOFF_EVENT"; break;

	case CTRL_SHUTDOWN_EVENT:
		PLOGI << "CTRL_SHUTDOWN_EVENT"; break;

	default:
		PLOGW << "Unknown signal:" << signal;
	}


	SetEvent(closeEvent);

	return TRUE;
}

void onSigint(int value) {
	PLOGI << "sigint handled"; // do cleanup
	SetEvent(closeEvent);
}

void atExitFunc(void)
{
	PLOGI << "atExitFunc"; // do cleanup
	SetEvent(closeEvent);
}

int wmain(int argc, TCHAR* argv[])
{
		PLOGI << "Press CTRL-C to unload and exit";
		closeEvent = CreateEvent(NULL, TRUE, FALSE, NULL);
		atexit(atExitFunc);
		signal(0xFFFF, onSigint);
		SetConsoleCtrlHandler(consoleHandler, TRUE);

		WaitForSingleObject(closeEvent, INFINITE);

		CloseHandle(closeEvent);

		PLOGI << "Closing, cleanup.";
                // Cleanup done here

}
