43/** @page pg_guest_lib VirtualBox Guest Library
44 *
45 * This is a library for abstracting the additions driver interface. There are
46 * multiple versions of the library depending on the context. The main
47 * distinction is between kernel and user mode where the interfaces are very
48 * different.
49 *
50 *
51 * @section sec_guest_lib_ring0 Ring-0
52 *
53 * In ring-0 there are two version:
54 * - VBOX_LIB_VBGL_R0_BASE / VBoxGuestR0LibBase for the VBoxGuest main driver,
55 * who is responsible for managing the VMMDev virtual hardware.
56 * - VBOX_LIB_VBGL_R0 / VBoxGuestR0Lib for other (client) guest drivers.
57 *
58 *
59 * The library source code and the header have a define VBGL_VBOXGUEST, which is
60 * defined for VBoxGuest and undefined for other drivers. Drivers must choose
61 * right library in their makefiles and set VBGL_VBOXGUEST accordingly.
62 *
63 * The libraries consists of:
64 * - common code to be used by both VBoxGuest and other drivers;
65 * - VBoxGuest specific code;
66 * - code for other drivers which communicate with VBoxGuest via an IOCTL.
67 *
68 *
69 * @section sec_guest_lib_ring3 Ring-3
70 *
71 * There are more variants of the library here:
72 * - VBOX_LIB_VBGL_R3 / VBoxGuestR3Lib for programs.
73 * - VBOX_LIB_VBGL_R3_XFREE86 / VBoxGuestR3LibXFree86 for old style XFree
74 * drivers which uses special loader and or symbol resolving strategy.
75 * - VBOX_LIB_VBGL_R3_SHARED / VBoxGuestR3LibShared for shared objects / DLLs /
76 * Dylibs.
