Right, there are obviously things that you cannot address with
a 'long', but there are potentially other things that you could
that you cannot address with an 'int', e.g. an opaque user
token (representing a user pointer) that you can get back in
the sample data.
In the worst case, you could still redefine the argument as a
transparent union to a long and pointer in the future if you
use a 'long' now. AFAICT, there are no advantages of using
an 'int' instead of a 'long', but there are disadvantages of
using a 'long long'.
