Pointers are addresses to locations in memory and thus lose their meaning after a program has terminated.</p><p>In principle, there is little point in storing a pointer to a file but in order to allow for a more seamless experience JLD2 will, similar to <code>Base.Serialization</code> silently accept pointers. This is useful when storing large structures such as a <code>DifferentialEquations.jl</code> solution object that might contain a pointer somewhere. Upon deserialization any pointer fields are instantiated as null pointers.</p><p>This is done with just three lines of code utilizing the custom serialization logic and  it is shown here as it serves as a good example for usage of that feature.</p><pre><code class="language-julia hljs">writeas(::Type{&lt;:Ptr}) = Nothing
