Audacious - OLD, PLEASE USE GITHUB DISCUSSIONS/ISSUES

If you just want to know how to declare the header and such:

#include <libaudcore/i18n.h>
#include <libaudcore/plugin.h>

class DummyPlugin : public GeneralPlugin
{
public:
    static constexpr PluginInfo info = {
        N_("A Useless Plugin"),
        PACKAGE
    };

    constexpr DummyPlugin () : GeneralPlugin (info, true) {}

    bool init ();
    void cleanup ();
};

EXPORT DummyPlugin aud_plugin_instance;

bool DummyPlugin::init ()
{
    return true;
}

void DummyPlugin::cleanup ()
{
}

Beyond that, it will vary depending on what type of plugin you are making.

I forgot to mention I want to write an input plugin.

The sndfile plugin is pretty clean; I'd suggest using that as an example.
