Hi,

I have developed a special network service for in-house use. All the  
details related to networking
and serializing infrastructure are written in c++. Basically, in c++ I  
ensure the TCP connection,
correctly receiving and sending messages, all the low level stuff.  
Now, I must give "power" to
my server by embedding one scripting language to let the final users  
of my service write their own
applications.

In this context, an application is a bunch of functions that all the  
Lua scripts must have. This functions
are called by the server. Much like implementing an abstract class. I  
see that working with Lua is very
easy and straightforward. But I am interested in one particular thing:  
I want to be able to instantiate
an object in Lua and keep it in c++. This object is like a session for  
the TCP connection that I'm handling.
So, if a receive a network request, I unpak the request into  
meaningful c++ structure an pass this
structure to Lua, along with the session above mentioned. This way,  
the guy that is writhing a Lua application
for may server is able to keep his own custom state for his  
application.In c++ this session object is opaque.

So, the question is: Can Lua build such an opaque object and maintain  
it after  lua_close(...)?



Thank you!

P.S.: I know I should read the docs and find the answer by myself, but  
I don't have the time to do it.
Only thing I want is an yes or no and after that I will read the docs  
because I will need it.
