The Janus Lua plugin implements all the mandatory hooks to allow the C code to interact with a custom Lua script, and viceversa. Anyway, Lua developers may want to have the C code do more than what is provided out of the box, e.g., by exposing additional Lua methods from C for further low level processing or native integration. This "extra" implementation provides a mechanism to do just that, as developers can just add their own custom hooks in the C extra code, and the Lua plugin will register the new methods along the stock ones.

More specifically, the Janus Lua plugin will always invoke the janus_lua_register_extra_functions() method when initializing. This means that all developers will need to do to register a new function is adding new lua_register calls to register their own functions there, and they'll be added to the stack.
