by Jerry McIntosh

---

INTRODUCTION

This is an Assembly Language implementation of a ByteBuffer. The ByteBuffer is implemented as a shared-library. There is also a C demo program.

LIST OF REQUIREMENTS:

• Linux OS
• Programming languages: Assembly, C
• Netwide Assembler (NASM), GCC compiler, and the make utility
• your favorite text editor
• and working at the command line

---

CREATE THE DEMO

Run the following command in the ByteBuffer-main folder:

sh ./bytebuffer_make.sh

---

RUN THE DEMO

In the demo folder enter the following command:

./go_demo.sh

---

THINGS TO KNOW

You can modify a define in the C header file main.h:

#define BUFFER_SIZE    256

Modifying the define will change the amount of memory allocated to the ByteBuffer.

You can uncomment the define BB_DEBUG to display debug output from the demo program.

Remember to recompile the demo program should you modify it:

In the ./demo folder enter the following:

make clean; make

Have Fun!
