Adding custom ("Hello") system call: help

What ends up in /var/log/messages is controlled in software by your system logger. It may or may not be syslog-ng. dmesg does end up there in my systems but that's by no means mandatory!
You seem to be getting some parts of dmesg in messages, but not your 'hello', possibly because it's just an 'alert' and not anything critical. the system logger is able to tell the different levels of criticality apart.
So, it's working.
All the really tough stuff actually went as planned. Be happy.

expackf
expackf(3alleg4) Allegro manual expackf(3alleg4) NAME
expackf - Using custom PACKFILE vtables. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example expackf DESCRIPTION
This program demonstrates the use of the packfile functions, with some simple tests. The first test uses the standard packfile functions to transfer a bitmap file into a block of memory, then reads the bitmap out of the block of memory, using a custom packfile vtable. The second test reads in a bitmap with another custom packfile vtable, which uses libc's file stream functions. The third test demonstrates seeking with a custom vtable. The fourth test reads two bitmaps, and dumps them back into a single file, using a custom vtable again. Tools SEE ALSO
