My main thread is used
also to declare some Lua callbacks needs to be called when an MQTT data
arrived. So I keep a reference to this function using classical luaL_ref().
Now, my problem : an MQTT
data arrives and is handled by another thread, on which I need to created a
dedicated Lua_State for this newly created thread. But how can I retrieve then
launch this function in the new lua_state.
Because, for the moment,
I'm retrieving the function from the main state, using xmove() it to the new
one and this call it ... obviously, it's crashing as the main state may be
busy by other tasks.
In addition, I don't want
to block the main thread using mutex as I don't want to have to rely on main
So any idea welcome :)
