Classic AmigaOS Programming

The number of Amigas with a network connection has been growing steadily. This is in no small part helped by projects like PiStorm and Plipbox that add a network device that can be used by any Amiga network stack. At the same time projects like AmiSSL allow the Amiga to use current encryption standards to securely connect over the Internet. More and more people being able to connect their Amiga to the Internet means that adding a networking option to games and other software is no longer serving just a small number of users. This book is aimed at coders who are familiar with creating software for the OS of the classic Amiga but have no experience with using the network and the Internet in their programs. The book assumes that there already is a working Internet connection on the Amiga. For Amigas that are emulated with WinUAE there is a short appendix that shows how to enable the built-in network stack of WinUAE. This book consists of four parts. The first part dives into how the network works, explaining the basics of addressing, routing and the IP protocol. This is followed by the part about network programming using sockets on the Amiga, which includes examples in C as well as in assembly language. The third part acts as a primer on encryption, concentrating mainly on how this is used by SSL/TLS. The book's last part shows how to use the AmiSSL library to create encrypted connections on the Amiga, again with examples in C and assembly. The C examples can be cross-compiled with GCC or even compiled natively with VBCC. The assembly examples have been tested with Asm-Pro as well as HiSoft DevPac.
