     char s[] = "filename.ext";

But hey, it's simpler, faster, less code, less bug prone, easier to understand 
and uses less memory to:

1. strlen
2. allocate
3. memcpy
4. append a 0
    foo
5. free

instead, right?

I know you said "just allocate a large fixed size buffer", but I hope you 
realize that such practice is the root cause of most buffer overflow bugs, 
because the "640K is enough for anyone" just never works.

And your "just use a struct" argument also promptly falls apart with:

     foo("string")

Now, I know that you'll never concede destruction, after all, this is the 
internet, but give it up :-)
