48	/** @page pg_guest_lib VirtualBox Guest Library
49	*
50	* This is a library for abstracting the additions driver interface. There are
51	* multiple versions of the library depending on the context. The main
52	* distinction is between kernel and user mode where the interfaces are very
53	* different.
54	*
55	*
56	* @section sec_guest_lib_ring0 Ring-0
57	*
58	* In ring-0 there are two version:
59	* - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
60	* who is responsible for managing the VMMDev virtual hardware.
61	* - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
62	*
63	*
64	* The library source code and the header have a define VBGL_VBOXGUEST, which is
65	* defined for VBoxGuest and undefined for other drivers. Drivers must choose
66	* right library in their makefiles and set VBGL_VBOXGUEST accordingly.
67	*
68	* The libraries consists of:
69	* - common code to be used by both VBoxGuest and other drivers;
70	* - VBoxGuest specific code;
71	* - code for other drivers which communicate with VBoxGuest via an IOCTL.
72	*
73	*
74	* @section sec_guest_lib_ring3 Ring-3
75	*
76	* There are more variants of the library here:
77	* - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
78	* - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
79	* drivers which uses special loader and or symbol resolving strategy.
80	* - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
81	* Dylibs.
