How is string passed from Lua to C

[rahul sharma <rahulatgslab@...>]

Hi,

Can anyone explain me how the string fetching is done by Lua. I want to pass string from Lua to C. I am able to access it using gettable and then converting it to string using lua_tostring(). But I don't know whether a new copy of that string is made on stack or its a reference to the string's location. If anyone knows about it, do let me know. My basic motto is to avoid the copy of data.

Thanks and Regards
