You have got a static struct, but I have got a dynamic structure, that is called n-times like
luareg.register( functionname, functionpointer )

So the register is called n-times and should register the function on the Lua state. Can I overwrite
existing function? I found the luaL_newlibtable & luaL_newlib in both ways it creates a new table.
If I use it with equal data two times, overwrite the call the existing table?

Thanks
