Porting Linux applications to 64-bit systems
Linux was one of the first cross-platform operating systems to use 64-bit processors, and now 64-bit systems are becoming commonplace in servers and desktops. Many developers are now facing the need to port applications from 32-bit to 64-bit environments. With the introduction of Intel® Itanium® and other 64-bit processors, making software 64-bit-ready has become increasingly important.
