So to david nugent do I speak these words:

I may be wrong here... but it seems that with something like this, you
wouldn't be able to have space already set aside for the destination of the
string, since you'd loose the pointer when it got overwritten by the value
returned by the function. You'd have to transfer the string from the
address returned by the funtion, into the location you want.

The second example (which I removed) avoids this by getting you to pass a
pointer to the string. Is there any way of finding out where the returned
value will be going? This would allow you to write directly to the
destination of the string, avoiding the problem of having to copy the
string latter on. And without making it neccisary to supply the name of the
string.
