| Structures in Assembly Language Programs
| Structures in Assembly Language Programs
Structures, or records, are an abstract data type that
allows a programmer to collect different objects together into a
single, composite, object. Structures can help make programs easier to
read, write, modify, and maintain. Used appropriately,... Read More >> |

| Linux terminal windows
Terminals are text oriented and introducing pictures or windows isn't attempted by most Linix utilities. Usually it is too much work for little benifit. But, there are a few ways we can cheat. One way is to use the drawing characters to make ... Read More >> |

| GetDriveType API Hooker (GUI)
Well, as you can see a simple API Hooker with nice GUI. I was too lazy to comment all the code, but I left enough spaces for it
to be readable for you guys. IMHO you will understand it easily since
it's all APIs, no unusual algos or whatever. Y...

| Introduction to GCC Inline Asm
| Introduction to GCC Inline Asm
The GNU C Compiler uses the assembler `as' as a backend. This assembler uses AT&T syntax. Here is a brief overview of the syntax.
For more information about `as', look in the system info
documentation.

| Brennan's Guide to Inline Assembly
| Brennan's Guide to Inline Assembly
Ok. This is meant to be an introduction to inline assembly under DJGPP.
DJGPP is based on GCC, so it uses the AT&T/UNIX syntax and has a somewhat
unique method of inline assembly. I spent many hours figuring some of
this stuff out and told I...

| Using Mode X via direct VGA access under Linux
| Using Mode X via direct VGA access under Linux
Accessing the VGA Card under Linux is different from DOS, the big difference
is that you can't use any VGA BIOS routines. So switching to the well known
320x200 Mode is more complicated, because you have to do all the work on your own.

| Using the raw keyboard mode under Linux
| Using the raw keyboard mode under Linux
If you read something from STDIN, the read bytes are normally in ASCII format.
In some cases it is useful to get the keyboard input as raw as possible.
Imagine: Your program should react on the Alt or Ctrl Key with menu
highlightning. In raw

| Using the audio device under Linux
| Using the audio device under Linux
The example code below is very simple. It doesn't check if your soundcard
supports the options required (44.1 kHz mono/stereo 16 Bits signed). This
causes wrong output if your soundcard doesn't support this. Of course your kernel
has to ha...

| Using self modifying code under Linux
I know that this is not the cleanest way of programming, but sometimes this
programming style is faster. Furthermore this method is used by JIT (just in time) compilers.
Transmeta also uses some sort of self modifying code to implement a x86
