You can do this with fork. A given parent can fork as may times as it wants. However, I agree with AviD pthreads may be more appropriate.

  secondChild = fork();
  if(secondChild > 0)
  {
    // In parent
  }
  else if(secondChild < 0)
  {
    // Error
  }
  else
  {
    // In secondChild
  }
}
else if(firstChild < 0 )
{
  // Error
} 
else
{
  // In firstChild
}
