REAPER calls a control surface through the IReaperControlSurface interface (defined in reaper_plugin.h) which a plugin has to register on startup. The function names of this interface are very similar to the CSurf_* functions, they just work the other way round (from REAPER to the plugin).
Parameters
MediaTrack* trackid, double volume, bool relative, bool allowGang
