Closes a specific user handle.

Syntax

void XUserCloseHandle(  
         XUserHandle user  
)

Parameters

user _In_
Type: XUserHandle

The user handle to close.

Return value

Type: void

Remarks

You must call the XUserCloseHandle function just once for each XUserHandle you retrieve from an XUser API. You can also close all handles that represent the user by calling the XUserCloseHandle function.

The following example demonstrates how to asynchronously add a user to a game session.

HRESULT AddUserComplete(XAsyncBlock* ab)
{
    unique_user_handle user;
    RETURN_IF_FAILED(XUserAddResult(ab, &user));

    XUserLocalId userLocalId;
    XUserGetLocalId(user.get(), &userLocalId);

    auto iter = std::find_if(
        _users.begin(),
        _users.end(),
        [&userLocalId](const User& candidate)
    {
        XUserLocalId candidateUserLocalId;
        XUserGetLocalId(candidate.Handle(), &candidateUserLocalId);
        return candidateUserLocalId == userLocalId;
    });

    // User already known
    if (iter != _users.end())
    {
        appLog.AddLog("User already in list\n");
        return S_OK;
    }

    try
    {
        _users.emplace_back(user.get());
        _users.back().LoadGamerPicAsync(_queue);
    }
    CATCH_RETURN();

    return S_OK;
}

HRESULT AddUser(bool allowGuests, bool silent)
{
    auto asyncBlock = std::make_unique<XAsyncBlock>();
    ZeroMemory(asyncBlock.get(), sizeof(*asyncBlock));
    asyncBlock->queue = _queue;
    asyncBlock->context = this;
    asyncBlock->callback = [](XAsyncBlock* ab)
    {
        auto asyncBlock = std::unique_ptr<XAsyncBlock>(ab);
        LOG_IF_FAILED(static_cast<UserWindow*>(ab->context)->AddUserComplete(ab));
    };

    XUserAddOptions options = XUserAddOptions::None;

    if (allowGuests)
    {
        WI_SET_FLAG(options, XUserAddOptions::AllowGuests);
    }

    if (silent)
    {
        WI_SET_FLAG(options, XUserAddOptions::AddDefaultUserSilently);
    }

    if (SUCCEEDED_LOG(XUserAddAsync(
        options,
        asyncBlock.get())))
    {
        // The call succeeded, so release the std::unique_ptr ownership of XAsyncBlock* since the callback will take over ownership.
        // If the call fails, the std::unique_ptr will keep ownership and delete the XAsyncBlock*
        asyncBlock.release();
    }

    return S_OK;
}
