1. Linux Question
Sorry to interrupt the debate.
Can anyone explain to me.
If I write a program using a Linux I/O so library that
requires the user to have Super User permissions to
run the program. Then if I statically link library and the program
will the program still require these same permissions.
If this is true then how can anyone write software that can be
used by all users on a linux system.

-rwxr-xr-x permissions for the file.
chmod 755 my-library.so ?
maybe I misunderstand your question or Linux, my Linux is as rough as my
Windows.

Turning off execute privileges on the .so for everyone doesn't affect
the operation at all.
If the shared library is readable by others, it'll work.
If no one but the owner can read it, then only it won't.

Oops. That's what I meant in my previous post, too.
-rwxr--r--
chmod 744, right?
