Hey dark byte,
Is there any method to use a thread?
After running a test:
3.5 seconds update, each update made in a thread (new thread in our case).
After about 20 hours of running it, I'm starting to get this error
Code:
Error:Thread creation error: Not enough storage is available to process this command.

No idea, if you free the thread properly (and all the objects you create inside it) it shouldn't cause a problem.

What you could do is create a thread that handles a message loop constantly until it receives a message that it should kill itself

e.g:
Code:

pipename="something"

commandhandler={}
commandhandler[0]=function(state) print("Command 0 is being handled") end
commandhandler[1]=function(state) print("This is command 1") end
commandhandler[2]=function(state) print("Executing command 2 which got as extra parameter "..state.pipe.readDword())  end
commandhandler[3]=function(state) print("This is command 3, which is to tell the thread to go kill itself") state.running=false end

function handler(t)
  local pipe=connectToPipe(pipename)
  local state={}
  state.running=true;
  state.thread=t
  state.pipe=pipe


  while (pipe.Connected and state.running) do
    print("Thread: Waiting for command");

    local command=pipe.readByte()

    if (command==nil) then
      print("Thread: readByte failed\n")
      break;
    end

    print(string.format("Thread: Received command %d", command))

    if (commandhandler[command]~=nil) then
      commandhandler[command](state)
    else
      print("Thread: Unknown command received. Aborting");
      break
    end
  end

  print("Thread: Thread exiting")
  pipe.destroy()
end

com=createPipe(pipename)
createNativeThread(handler)
com.acceptConnection()

com.writeByte(0)
com.writeByte(1)
com.writeByte(2) com.writeDword(1234567)
com.writeByte(3)

A script that usages the pipe class and color gradient, colorful GUI Smile.
