plugintest - dynamic loader example Colin King [email protected]

This is a small demonstration of Unix-style dynamic loading. This is a powerful feature of the C library that allows you to write and load plugins into your applications. There are many ways to do this through frameworks, but this seems to be the simplest.

This compiles in Linux and possibly FreeBSD.
