table to userdata

[torch blue <bluetorchgames@...>]

Hi,

 

A quick question. What's the best way to fill a userdata with a table? for example, I have a table

config

{

length = 3,

width = 2,

color = "red"

}

 

and I have a structure in C, that I can expose to lua as a userdata.

class CConfig

{

int length;

int width;

string color

}

 

how do I fill the CConfig with  table config?

 

Thanks
