Plugin basics:

Your plugin should export the following symbols (functions):

extern "C" {
	int mythplugin_init (const char *libversion);
	int mythplugin_run ();
	int mythplugin_config ();

The plugin module is built as a shared object/dynamic link library.  The 
mythplugin_init() function is called (once) when the module is initially 
loaded into memory.  The mythplugin_run() function is the main function of 
your module.  The mythplugin_config() function is the main function for your 
module's setup gui.

That's the basics.  Take a look at the makefile and main.cpp file of any of 
the Myth modules for examples.
