Hi All,

How can I get the current state of the state machine?

Currently i am getting in this way.. i would like to know if there any
better way 

statemachine
---------------
struct StateMachine:sc::state_machine<StateMachine, Initial>
{

   void setState(string s){
     state = s; 
   }
   string getState()
   {
     return state;
   }
private:
   string state;
}

//event

struct dummyEvent:sc::event<dummyEvent>
{

}

//state

struct Initial:sc::simple_state&lt;Initial, StateMachine&gt;
{

 typedef mpl::list&lt;sc::custom_reactions&lt;dummyEvent&gt;> reactions;
  sc::result react(const dummyEvent&);
}

In react function of the 'Initial' state

sc::result Initial::react(const dummyEvent&)
{
  context <StateMachine>().setState("Initial");
}

In my main

main()
{
  StateMachine machine;
  machine.initiate()
  cout << "Current State "<< machine.getState() << endl; // return me the
current state
}

Thanks in adavance
justin
