Target 32- and 64-bit Platforms Together with a Few Simple Datatype Changes

n the early 1990s, 64-bit systems were considered "a solution waiting for a problem." In 2005, however, this technology is rapidly gaining a critical mass of users. Even if you're aiming at 32-bit platforms for the time being, adding 64-bit compliance to your coding checklist guarantees a smooth migration to 64-bit platforms in the future. This solution shows you how to write dually-targeted code.

How to write single-source code that can be deployed on both 32- and 64-bit environments without necessitating code rewriting?
