45	/** @page pg_guest_lib VirtualBox Guest Library
46	*
47	* This is a library for abstracting the additions driver interface. There are
48	* multiple versions of the library depending on the context. The main
49	* distinction is between kernel and user mode where the interfaces are very
50	* different.
51	*
52	*
53	* @section sec_guest_lib_ring0 Ring-0
54	*
55	* In ring-0 there are two version:
56	* - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
57	* who is responsible for managing the VMMDev virtual hardware.
58	* - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
59	*
60	*
61	* The library source code and the header have a define VBGL_VBOXGUEST, which is
62	* defined for VBoxGuest and undefined for other drivers. Drivers must choose
63	* right library in their makefiles and set VBGL_VBOXGUEST accordingly.
64	*
65	* The libraries consists of:
66	* - common code to be used by both VBoxGuest and other drivers;
67	* - VBoxGuest specific code;
68	* - code for other drivers which communicate with VBoxGuest via an IOCTL.
69	*
70	*
71	* @section sec_guest_lib_ring3 Ring-3
72	*
73	* There are more variants of the library here:
74	* - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
75	* - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
76	* drivers which uses special loader and or symbol resolving strategy.
77	* - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
78	* Dylibs.
