This should work:

#include <iostream>

#include <aspell/manager.hh>
#include <aspell/check.hh>
#include <aspell/config.hh>
#include <aspell/clone_ptr-t.hh>

int main() {
  using namespace aspell;

  Manager manager("");
  CheckState<string::const_iterator> state(manager);

  string line;
  vector<string> errors;

  getline(cin, line);
  line += '\n';

  state.restart(line.begin(), line.end());
  // initializes the state with the string
  // needs to be done when ever the string changed.

  while (state.advance(), 
	 // advanced the state from the last error or from the beggining
	 check(state), 
	 // checks the string stopping at the next error
	 !state.at_end()
	 // it the state is at the end there are no more errors
	 ) 
    {
      errors.push_back(state.word());
    }

  // print out all the errors.
  for (int i = 0; i != errors.size(); ++i) {
    cout << errors[i] << "\n";
  }

}


When compiling remember to link it with the aspell library using "-laspell".
The CheckState stuff is not very stable so be aware that this may change
a bit between releases.  Let me know if you have any other problems.
