<sect>Introduction

|

|
|
|
<p>We've tried to make BIRD as portable as possible, but unfortunately
|
|
|
|
|
communication with the network stack differs from one OS to another,
|
|
|
|
|
so we need at least some OS specific code. The good news is that this
|
|
|
|
|
code is isolated in a small set of modules:
|
|
|
|
|
|
|
|
|
|
<descrip>
|
|
|
|
|
<tagp><tt/config.h/</tagp> is a header file with configuration information,
|
|
|
|
|
definition of the standard set of types and so on.

|
|
|
<tagp/Startup module/ controls BIRD startup. Common for a family of OS's (e.g.,
|
2000-06-05 20:49:04 +08:00
|
|
|
for all Unices).
|
|
|
|
|
<tagp/Logging module/ manages the system logs. [per OS family]
|
|
|
|
|
<tagp/IO module/ gives an implementation of sockets, timers and the
|
|
|
|
|
global event queue. [per OS family]
|
|
|
|
|
<tagp/KRT module/ implements the Kernel and Device protocols. This
|
|
|
|
|
is the most arcane part of the system dependent stuff and some
|
|
|
|
|
functions differ even between various releases of a single OS.
