You can replace the above with:
name = luaL_checkstring(L,1);
underId = luaL_optinteger(L,2,0);
luaL_checkstring() and luaL_optinteger() will do the appropriate error
checking for you.

You might want to change the above line to:
lua_createtable(L,nodes.count,0);
This will size the array portion and might be a bit faster.

And here, you might want:
lua_createtable(L,0,5);
since you are creating a table with five fields. Again, might be a bit
faster.
