Set up invocation methods - XBOX Game Development Documentation

This topic provides an example of how to set up invocation methods for a custom provider. When working with custom async providers, it’s best to use invocation methods so that the provider can be reused as needed.

HRESULT CustomProviderMethodAsync(XAsyncBlock* async)
{
    // Set up the context for your method.
    void* context;
    HRESULT hr = XAsyncBegin(async, context, CustomProviderMethodAsync, __FUNCTION__,
        [](XAsyncOp op, const XAsyncProviderData* providerData)
        {
            // Provider cases are handled here.
            return S_OK;
        });
    return hr;
}

This example shows how all asynchronous Microsoft Game Development Kit (GDK) methods are implemented and allows for reuse of the provider. If the DoWork case is highly specific, it becomes a specialized asynchronous function. To make it generic, allow the DoWork case to be customized in some way.
