It will return when it has finished processing the code, with a return
code. You should use lua_pcall, because if you get an error with
lua_call your program with end with that error.

The global table (can use _G to access it):

function fun() return 42 end

Now _G['fun'] will reference the function.

No, because they are still referenced by the global table.
