Hello all,

I have a basic question about threads: can one assume that the thread is started
after the constructor call (or when using create_thread in thread groups) or
does one has to use an extra synchronization primitive (e.g. a barrier)? 

Example (real world is more complex):

void g(int* x)
{
  int x1 = *x;
}

void f()
{
   int x = 0;
   boost::thread thd(&g, &x);
   //<-- thread is started or not?
}
