This seems more like a C question then a Lua question.  But you can see an 
example here [1] of passing a Lua state to a thread.

If you just want to use threads from Lua try lua-llthreads [2].  See the 
example [3] that uses llthreads.

llthreads/blob/master/src/thread.nobj.lua#L180

llthreads/blob/master/examples/sub_threads.lua
