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