XPackageGetInstallationProgress

Returns the current progress of installation.

Syntax

void XPackageGetInstallationProgress(  
         XPackageInstallationMonitorHandle installationMonitor,  
         XPackageInstallationProgress* progress  
)  

Parameters

installationMonitor _In_
Type: XPackageInstallationMonitorHandle A handle to the installation monitor. progress _Out_
Type: XPackageInstallationProgress* On return, contains the current progress of installation.

Return value

Type: void

Remarks

To get the current progress of an installation, call XPackageGetInstallationProgress; to get notified of a change during an installation, register a callback. You may create the installation monitor for the whole package or a particular subset. For a moment during a fresh install of new content, the runtime can’t calculate the total size of the package, because the installation hasn’t started completely. In this case, the runtime will return UINT64_MAX as the value for totalBytes, and zero or false for all other fields. Example:

void CALLBACK ProgressChangedCallback(
    void* /* context*/,
    XPackageInstallationMonitorHandle monitor)
{
    XPackageInstallationProgress progress;
    XPackageGetInstallationProgress(monitor, &progress);

    if (progress.completed)
    {
        printf("Track ready\n");
        XPackageCloseInstallationMonitorHandle(monitor);
    }
}

HRESULT StartMonitoring(XTaskQueueHandle queue, char* trackName)
{
    char id[XPACKAGE_IDENTIFIER_MAX_LENGTH];

    HRESULT hr = XPackageGetCurrentProcessPackageIdentifier(_countof(id), id);
    if (FAILED(hr)) return hr;

    XPackageChunkSelector selector;
    selector.type = XPackageChunkSelectorType::Tag;
    selector.tag = trackName;

    XPackageInstallationMonitorHandle monitor;
    hr = XPackageCreateInstallationMonitor(
        id,         // Identity to be monitored
        1,          // Number of selectors
        &selector,  // Selectors
        1000,       // Resolution of the monitor, in milliseconds
        queue,      // Queue where updates are performed
        &monitor);
    if (FAILED(hr)) return hr;

    XTaskQueueRegistrationToken token;
    hr = XPackageRegisterInstallationProgressChanged(
        monitor,
        nullptr,
        ProgressChangedCallback,
        &token);

    if (FAILED(hr))
    {
        XPackageCloseInstallationMonitorHandle(monitor);
    }

    return hr;
}

Let’s walk through each API call in the code shown above:

XPackageGetCurrentProcessPackageIdentifier(_countof(id), id);

All installed content will have a unique identifier. You can monitor any package’s installation if you know the package’s identifier and have access to that content. A running process can get its own package identifier. For more information about package identifiers, see Manage and license downloadable content (DLC).

XPackageCreateInstallationMonitor( 
    id,         // Identity to be monitored 
    1,          // Number of selectors 
    &selector,  // Selectors 
    1000,       // Resolution of the monitor, in milliseconds 
    queue,      // Queue where updates are performed 
    &monitor); 

This creates a monitor that keeps track of the state of installation. This installation monitor updates itself on a regular cadence. To get the current progress of an installation, call XPackageGetInstallationProgress; to get notified of a change during an installation, register a callback. You may create the installation monitor for the whole package or a particular subset. Here, you have defined a “selector” that says you want to know about the installation progress for a track name. You can specify a frequency (in this case 1000 ms) that indicates how often the installation monitor will update its snapshot of progress, up to this speed. If no progress has been made in time, it could be slower.

hr = XPackageRegisterInstallationProgressChanged(
    monitor,
    nullptr,
    ProgressChangedCallback,
    &token);

You want to know when the track has finished loading, so you register a progress-change event on the monitor. This callback will be invoked through the task queue that was provided when the monitor was created, roughly at the cadence specified in XPackageCreateInstallationMonitor. Inside the callback, you can render in-game progress or notify the game that a track is ready. In this example, you close the installation monitor but don’t unregister the notification. The lifetime of an installation monitor notification is tied to the installation monitor; therefore, closing the monitor unregisters all notifications to it.
