VirtualBox

source: vbox/trunk/include/VBox/VBoxGuest.h@ 73768

Last change on this file since 73768 was 72627, checked in by vboxsync, 6 years ago

Additions: relicence components needed for Linux shared folders to MIT.
bugref:9109: Shared folders: update to match in-kernel code more closely
This change makes the code on which the Linux kernel shared folder patch is
based MIT-licenced, so that the version in the Linux kernel can be too. This
would make it easier to move code back and forth.
  • Property svn:eol-style set to native

49/** @defgroup grp_vboxguest_ioc VirtualBox Guest Additions Driver Interface
50 *
51 * @note This is considered internal in ring-3, please use the VbglR3 functions.
52 *
53 * - I/O controls for user and/or kernel mode starts at 0.
54 * - IDC specific requests descends from 127.
55 * - Bits 7 and 6 are currently reserved for future hacks.
56 *
57 * @remarks When creating new IOCtl interfaces keep in mind that not all OSes supports
58 * reporting back the output size. (This got messed up a little bit in VBoxDrv.)
59 *
60 * The request size is also a little bit tricky as it's passed as part of the
61 * request code on unix. The size field is 14 bits on Linux, 12 bits on *BSD,
62 * 13 bits Darwin, and 8-bits on Solaris. All the BSDs and Darwin kernels
63 * will make use of the size field, while Linux and Solaris will not. We're of
64 * course using the size to validate and/or map/lock the request, so it has
65 * to be valid.
66 *
67 * For Solaris we will have to do something special though, 255 isn't
68 * sufficient for all we need. A 4KB restriction (BSD) is probably not
69 * too problematic (yet) as a general one.
70 *
71 * More info can be found in SUPDRVIOC.h and related sources.
72 *
73 * @remarks If adding interfaces that only has input or only has output, some new macros
74 * needs to be created so the most efficient IOCtl data buffering method can be
75 * used.

468 * IOCTL to for acquiring and releasing guest capabilities.
469 *
470 * This is used for multiple purposes:
471 * 1. By doing @a acquire r3 client application (e.g. VBoxTray) claims it will
472 * use the given session for performing operations like @a seamless or
473 * @a auto-resize, thus, if the application terminates, the driver will
474 * automatically cleanup the caps reported to host, so that host knows guest
475 * does not support them anymore
476 * 2. In a multy-user environment this will not allow r3 applications (like
477 * VBoxTray) running in different user sessions simultaneously to interfere
478 * with each other. An r3 client application (like VBoxTray) is responsible
479 * for Acquiring/Releasing caps properly as needed.
480 *
481 *
482 * VERR_RESOURCE_BUSY is returned if any capabilities in the fOrMask are
483 * currently acquired by some other VBoxGuest session.
