I have heard of stdint.h but not inttypes.h
I just looked at one on a linux system, PRIdu4 does not seem to be
cross-platform. there IS a PRId64.
I looked it up, and I think I need to switch my way of using printf on
cross-platform. however, size_t is an icky one, because DJGPP does not support
size_t in printf. it is the one compiler that throws a monkey wrench into the
entire works.
I just found out that on 64-bit systems, size_t and size_type are 64-bit. on
32-bit systems they are 32-bit. this leaves me with #ifdef-ing my way through
a lot of my code. I would much rather be using some sort of macro that can
change its bit width depending on 32 or 64-bit at compile time, or use some
*standard* cout and printf ways of displaying size_t and size_type!
changeable data types make cross-platform coding a headache, as I am sure you
are well aware.
I would prefer some sort of standard OR some way I can standardize a way of
doing this. I think I have a way, I am making my own standard, a quprintf.h
file which has some #defines for STPRINTFD, STPRINTFU, SZTPRINTFD, SZTPRINTFU.
too bad the standard says that the definition in any particular compiler of
size_t should not be relied upon.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
