Discover why you need to change your applications and build environments that supply 32-bit-only kernel extensions to accommodate IBM AIX® Version 6. With AIX Version 6, the kernel environment is 64-bit kernel only. Previously, the AIX operating system provided both 32-bit and 64-bit kernels, requiring 32-bit and 64-bit kernel extensions. In this article, apply two easy solutions to help you make the transition and start reaping the benefits of the simplified kernel environment.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
