LibBSD Usage

17.2.1. LibBSD Usage#

This chapter is thought for people who want to mainly use LibBSD in an application. It describes basic initialization and how to use various features of LibBSD.

FIXME: This documentation is still under construction. Contributions are welcome.

17.2.1.1. Basics#

There are two basic configuration models:

  1. Using a configuration that is as close as possible to the FreeBSD configuration. That usually means that you create a /etc/rc.conf and some other configuration files. Advantage of this model is that it is simple and straightforward. Usually the FreeBSD documentation can be used to find out how to configure something. The disadvantage is that the configuration is not known at compile time and therefore extra code has to be linked in which results in bigger code sizes. This method is recommended for systems that do not have serious memory limitations.

  2. Alternatively it is possible to do the configuration with calls to certain functions (like ifconfig). Disadvantage is that this needs a lot more detail knowledge about the internals of LibBSD and what has to be initialized. The advantage is that the linker can remove unused code and therefore it is more suitable for systems with a relatively small memory footprint.
