/*
* http://www.lua.org/manual/5.1/manual.html#lua_CFunction
*
* In order to communicate properly with Lua, a C function must use the following protocol,
* which defines the way parameters and results are passed: a C function receives its arguments
* from Lua in its stack in direct order (the first argument is pushed first). To return values to Lua,
* a C function just pushes them onto the stack, in direct order (the first result is pushed first),
* and returns the number of results. Any other value in the stack below the results will be properly
* discarded by Lua. Like a Lua function, a C function called by Lua can also return many results.
