RE: Function lua_register

["Peter Prade" <prade@...>]

Hi!

you might want to take a look at tolua
(http://www.tecgraf.puc-rio.br/~celes/tolua/)
or one of the other code wrappers on the page http://www.lua.org/addons.html

what tolua does, it creates a wrapper function that does all the dirty work
for you ;)

if you have a C function, let's say:

	int calculate(int a, int b);

then tolua creates a wrapper function for it so that you can call it in lua
with two number arguments:

	print(calculate(1,2))

the hard way is to get the arguments from the stack by hand. not good for
readability and you have all kinds of possible pitfalls (like the trailing
nil problem with a lot of the standard library functions etc.)

Regards,
Peter
