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.
