Updater Library

The Updater Library is the library we use to provide automatic updates to users of all of our applications. It's currently in-use in both Decoda and the Natural Selection 2 tools alpha.

In addition to handling patches, the Updater Library also includes functionality to send exception/crash and other types of reports.

The Updater Library can be used in a number of different ways; synchronous or asynchronous, and with the built in UI or a custom GUI.

Basic usage:

const unsigned int buildNumber = 100;
const char* buildsUrl = "http://www.unknownworlds.com/builds.xml";
Updater updater;   
if (updater.CheckForUpdates(buildsUrl, buildNumber, NULL))
{
    if (updater.ShowUpdateNotice(NULL))
    {
    
        if (!updater.DownloadUpdate(NULL))
        {
            printf("Error downloading update");
            return;
        }
        if (!updater.InstallUpdate())
        { 
            printf("Error running installer");
            return;
        }
        else
        {
            // Terminate the process so the updater will start.
            exit(0);
        }
    }
}

The Updater downloads an XML file from a server to get information about the builds and patches available.
