but what you can do to get the info is :
if(std::distance(tok.begin(), tok.end()) < 3)
      {
              std::cout << "not enough arguments\n";
              exit(1);
      }
arg1=*pos++;
      arg2=*pos++;
      arg3=*pos++;
Alternatively, you could write a next() function:

template<typename It>
inline typename std::iterator_traits<It>::value_type next(It &first, It 
&last)
{
  if(first == last) {
    throw something;
  }
  return *first++;
}

And then just do:

arg1 = next(pos, end);
arg2 = next(pos, end);
arg3 = next(pos, end);
