By phord:

The `char buffer[]` or the `string str` is redundant. You could easily build the string into `str` from the beginning. I would find it more readable that way, myself.

Just a thought.

```c++
string str;
str = "==> " ;
str += m_filename;
str += "<==\n";
print_to_stdout( str.c_str() ) ;
```

Or you could even use stringstream:

```c++
std::stringstream ss;
ss << "==> " << m_filename << " <==\n";
print_to_stdout( ss.str().c_str() ) ;
```
