In the Advanced User's Guide pp 5-6 there is an example showing
how to allocate storage for a string by allocating a pointer
to an array of characters. The size of that arrayy is 1 plus the
length of the string to put in it (because strings are null terminated).
After making that pointer, they use (setf (foreign-string-value <pointer>) <string>)
to copy the <string> into the newly allocated storage.

In page 5-42, the same thing is done but the length of the array is set to 8.
The example also shows (setf (foreign-string-value <pointer>) "12345678")

Question: Assuming that "12345678" is also null terminated, why the second array
is of size 8 and not 9 as the first example suggests?
