[PATCH 5/7] examples: fix incompatible type casts

[mhorne at FreeBSD.org]

From: Mitchell Horne <mhorne at FreeBSD.org>

Some printf statements in the API demo assume pointers to be 32-bits
long, presumably since it was originally developed for 32-bit arm. This
generates a number of warnings when compiling for 64-bit architectures,
and may result in truncation of these values. Fix this by avoiding casts
where possible or casting to a more appropriate type.
