Well, you konw there’s GetLastError(). But how can you get the last error AS A STRING? Use FormatMessage()!


Please be sure to LocalFree() returned result when you are done
with the string returned.

LPSTR GetLastErrorString()
  LPSTR buf = NULL ;

  int result = FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER |
                 0 );

  return buf ;

// Use above function with this one, so you don't have to
// worry about calling LocalFree
void printLastError( char *msg )
  LPSTR error = GetLastErrorString() ;
  printf( "%s %s\n", msg, error ) ;
  LocalFree( error ) ;
