thanks for yours quickly response.

I use tool tolua++ bind a C++ class to lua, and found that it expose a instance of class to lua, so confused whether it is reentrantable for lua script.

in my scenario, I will create many instance of the class in lua script, tolua++ can support that? and how to write a entrantable library? it is my question.

I did not have any problems using lua from multiple threads
on a multi-cpu machine running windows .
The interface was implemented using the excellent
luabind library.

You must make sure that a single luastate (and therefore
all the calls that use luastate) is not used by multiple threads
at the same time, in my instance, each thread on startup was setup
to have a luastate.  So the same luastate would be used by only that

So 5 threads, 5 luastates that are permanently attached to each thread.
