+/// <summary> Async communication within the plugin system
+/// Due to the asynchronous nature of plugins, combined with the limitations of multi-compiler support
+/// and the custom memory allocator used by r2, is it difficult to safely get data across DLL boundaries
+/// from Northstar to plugin unless Northstar can own that memory.
+/// This means that plugins should manage their own memory and can only receive data from northstar using one of the functions below.
+/// These should be exports of the plugin DLL. If they are not exported, they will not be called.
+/// Note that it is not required to have these exports if you do not use them.
+/// </summary>
