none worked :(
neither the boost::this_thread::get_id() is useable in a switch statement , nor the suggested use of boost::thread* or boost::container::vector<thread> .

before i give the faulty source code of mine , i need to answer what exactly im after .
see some of my friends are trying to learn boost , specially to work with its threading capabilities to use it in a project of theirs . they have no idea what boost is , or how these stuff work , so its on me , because unlike them i had a little experience with boost in a long past .
so one of them asked me a question on a scenario where there is a function , which is reapeately creating new threads , and each thread execute a function with a unique request message ,
in the aforementioned function ( dispatcher lets say ) , he wants to see if he as a ability to distinguish between the coming threads , and altering them at any given moment , be it terminating them , or simply getting its Id for further management , again by management i mean , in other functions ( or objects methods ) the thread can be specified by its ID , for being recognized for being surveyed , or again being terminated or moved .

and i also have another question , how do i send an argument to afunction with is goingto be used as packaged_task? it seems , i can only make packaged_task objects out of strucs! or classes! seems i cant even use functions at all! is it right ? i would appreciate an explanation on this matter too please .

and now here is the source :
i am on windows 7 sp1 - 32bit - Visual studio 2010 .

#include <boost/signal.hpp>
#include <iostream>
#include <boost/thread.hpp>
using namespace std;

boost::thread* threadarray[3];

int t(int x)
{
    switch(boost::this_thread::get_id())
    {
    case threadarray[0].get_id():
       cout<<"thread 1";
       break;
       case threadarray[1].get_id():
       //DISPOSE THIS THREAD or CHANGE OWNERSHITP, OR GET ANOTHER JOB TO IT , OR CHECK IF IT WAS SUCCESSFUL OR NOT
       cout<<"thread 2";
           break;
       case threadarray[3].get_id():
       cout<<"thread 3";
       break;
       default:
           cout<<"default";
    }
    return 0;
}

int main()
{
    boost::thread t1(t,5), t2(t,6),t3(t,7);

    threadarray[0] = t1.move();
    threadarray[1] = t2.move();
    threadarray[2] = t3.move();

    for(int i = 0; i <3;i++)
    {
       threadarray[i].join();
    }
    system("pause");
}

and these are the errors:
