[Boost-users] interrupt a blocking stream read

I am attempting to interrupt a blocking stream read.

The below code doesn't work since std::istream::read is not a valid
boost thread interruption point.

Can someone recommend a way to get something like this work work,
preferably using boost's cross-platform constructs?

Thank you,

Chris

void f()
{
  try
  {
    char c[999999999];

    cin.read(c, 999999999);
  }
  catch (boost::thread_interrupted)
  {
  }
}

int main()
{
  boost::thread t(f);

  f.interrupt();

  f.join()

  return 0;
}
