/** /**
* DataPacks are a way to store and move around various types of data in AMX Mod X Scripting. * Datapack tag declaration
* Since some things are not possible in AMX Mod X, such as a function consuming a String, *
* DataPacks help us get these Strings and other items where they need to go. * @note Datapacks provide a way to store and move around arbitrary amounts (and
* types) of data in AMX Mox X. Data is packed into a single cell value -
* the DataPack handle. This handle can be passed around more easily, can
* be returned by functions and can simulate advanced concepts like string
* consummation.
* @note Plugins are responsible for freeing all datapack handles they acquire.
* Failing to free handles will result in the plugin and AMXX leaking
* memory.
