guest additions for VirtualBox contain usually of two parts: The
guest kernel-level drivers for communication with the host and
guest userland applications making use of the services provided
by the guest kernel-level drivers.
The startpoint for developing VBox guest additions is
VBoxGuest is the guest kernel-level driver.
Maybe you want to start understanding the implementation for Linux,
VBoxGuest.cpp (the common part for all supported OSes) and VBoxGuest-linux.c.
The next step would be to have a look into
which is the guest userland service providing time synchronization,
guest statistics and so on.
Sorry, but there is no written documentation so you have to go through the
