Function Documentation

StartupThreads()

void StartupThreads	(	const dca::DcaInstance &	aDcaInstance,
		const dca::UpdateModule &	aUpdateModule,
		volatile bool *	schedulerErrorSignal,
		volatile bool *	performUpdateErrorSignal
	)

Starts up the update and schedule threads and supplies the given DcaInstance and UpdateModule.

Parameters

[in]	aDcaInstance	An initialized DcaInstance
[in]	aUpdateModule	An initialized UpdateModule
[out]	schedulerErrorSignal	If an UpdateModule::performUpdate() call encounters an error this bool will be set to true, and the main application will shut down.
[out]	performUpdateErrorSignal	If an DcaInstance::schedule() call encounters an error this bool will be set to true, and the main application will shut down.

Starts up two threads

• an update thread that calls the aUpdateModule::performUpdate() method in a loop and
• a schedule thread that calls the aDcaInstance::schedule() method in a loop.

The called functions will check engine and content updates automatically and install them in the provided dca/init directory.

They will be stopped by a call to ShutdownThreads()

ShutdownThreads()

void ShutdownThreads

(

)

Shuts down the previously started update and schedule threads.

Shutting down will stop the threads safely.

If an update is already in progress the function will return as soon as possible but will not force-terminate any thread.

Note

To force stop any running update processes immediately a call to DcaInstance::signal() should be invoked.
