Remarks

Note

This function isn't safe to call on a time-sensitive thread. For more information, see Time-sensitive threads.

XPackageGetMountPath mounts the specified package identifier and returns a mount handle to it. This might take several seconds. For more information about package identifiers, see Manage and license downloadable content (DLC).

Together, XPackageGetMountPath and XPackageGetMountPathSize are used to return the file path to a package's contents.

Only content packages can be mounted. An attempt to mount another game will yield E_ACCESS_DENIED.

The following code example shows how packages are usually mounted:

HRESULT MountDlc(char* dlcIdentifier)
{
    XPackageMountHandle mountHandle;
    HRESULT hr = XPackageMount(dlcIdentifier, &mountHandle);
    if (FAILED(hr)) return hr;

    size_t pathSize;
    hr = XPackageGetMountPathSize(mountHandle, &pathSize);
    if (FAILED(hr))
    {
        XPackageCloseMountHandle(mountHandle);
        return hr;
    }

    char* path = new (std::nothrow) char[pathSize];
    if (path == nullptr)
    {
        XPackageCloseMountHandle(mountHandle);
        return E_OUTOFMEMORY;
    }

    hr = XPackageGetMountPath(mountHandle, pathSize, path);
    if (FAILED(hr))
    {
        XPackageCloseMountHandle(mountHandle);
        delete[] path;
        return hr;
    }

    printf("Dlc %s mounted at path %s\n", dlcIdentifier, path);

    delete[] path;

    // Unmounts DLC path if this is the last handle
    // to it.
    XPackageCloseMountHandle(mountHandle);
    return S_OK;
}
