295 * For pointers without alpha channel the XOR mask pixels are 32 bit values: (lsb)BGR0(msb).
296 * For pointers with alpha channel the XOR mask consists of (lsb)BGRA(msb) 32 bit values.

298 * Guest driver must create the AND mask for pointers with alpha channel, so if host does not
299 * support alpha, the pointer could be displayed as a normal color pointer. The AND mask can
300 * be constructed from alpha values. For example alpha value >= 0xf0 means bit 0 in the AND mask.
301 *
302 * The AND mask is 1 bpp bitmap with byte aligned scanlines. Size of AND mask,
303 * therefore, is cbAnd = (width + 7) / 8 * height. The padding bits at the
304 * end of any scanline are undefined.
305 *
306 * The XOR mask follows the AND mask on the next 4 bytes aligned offset:
307 * uint8_t *pXor = pAnd + (cbAnd + 3) & ~3
308 * Bytes in the gap between the AND and the XOR mask are undefined.
309 * XOR mask scanlines have no gap between them and size of XOR mask is:

1169/** @name VBoxGuest IOCTL codes and structures.
1170 *
1171 * The range 0..15 is for basic driver communication.
1172 * The range 16..31 is for HGCM communcation.
1173 * The range 32..47 is reserved for future use.
1174 * The range 48..63 is for OS specific communcation.
1175 * The 7th bit is reserved for future hacks.
1176 * The 8th bit is reserved for distinguishing between 32-bit and 64-bit
1177 * processes in future 64-bit guest additions.
1178 *
1179 * While windows IOCTL function number has to start at 2048 and stop at 4096 there
1180 * never was any need to do this for everyone. A simple ((Function) | 0x800) would
1181 * have sufficed. On Linux we're now intruding upon the type field. Fortunately
1182 * this hasn't caused any trouble because the FILE_DEVICE_UNKNOWN value was set
1183 * to 0x22 (if it were 0x2C it would not have worked soo smoothly). The situation
1184 * would've been the same for *BSD and Darwin since they seems to share common
1185 * _IOC() heritage.
1186 *
1187 * However, on good old OS/2 we only have 8-bit handy for the function number. The
1188 * result from using the old IOCTL function numbers her would've been overlapping
1189 * between the two ranges.
1190 *
1191 * To fix this problem and get rid of all the unnecessary windowsy crap that I
1192 * bet was copied from my SUPDRVIOC.h once upon a time (although the concept of
1193 * prefixing macros with the purpose of avoid clashes with system stuff and
1194 * to indicate exactly how owns them seems to have been lost somewhere along
1195 * the way), I've introduced a VBOXGUEST_IOCTL_CODE for defining generic IN/OUT
1196 * IOCtls on new ports of the additions.
1197 *
1198 * @remarks When creating new IOCtl interfaces keep in mind that not all OSes supports
1199 * reporting back the output size. (This got messed up a little bit in VBoxDrv.)
1200 *
1201 * The request size is also a little bit tricky as it's passed as part of the
1202 * request code on unix. The size field is 14 bits on Linux, 12 bits on *BSD,
1203 * 13 bits Darwin, and 8-bits on Solaris. All the BSDs and Darwin kernels
1204 * will make use of the size field, while Linux and Solaris will not. We're of
1205 * course using the size to validate and/or map/lock the request, so it has
1206 * to be valid.
1207 *
1208 * For Solaris we will have to do something special though, 255 isn't
1209 * sufficent for all we need. A 4KB restriction (BSD) is probably not
1210 * too problematic (yet) as a general one.
1211 *
1212 * More info can be found in SUPDRVIOC.h and related sources.
1213 *
1214 * @remarks If adding interfaces that only has input or only has output, some new macros
1215 * needs to be created so the most efficient IOCtl data buffering method can be
1216 * used.
