I am afraid you cannot allow the direct access to the internal buffer of
a string if this buffer can be implicitly shared between different
instances as it is the case with QString. Because when you want to make
some modification or want to get a non-const pointer to this buffer, its
content has to be copied if the buffer is shared between a few copies.

On the other hand, I don't see what is the problem with using C string
routines with it. ::data() returns a pointer and :capacity () returns
allocated size of the buffer. ::resize() changes the size of the string.
If you need a greater allocated size, you can use ::reserve().
Or did I miss something?
