13 The protocol tree related functions.<BR>
14 A protocol tree will hold all necessary data to display the whole dissected packet.
15 Creating a protocol tree is done in a two stage process:
16 A static part at program startup, and a dynamic part when the dissection with the real packet data is done.<BR>
17 The "static" information is provided by creating a hf_register_info hf[] array, and register it using the
18 proto_register_field_array() function. This is usually done at dissector registering.<BR>
19 The "dynamic" information is added to the protocol tree by calling one of the proto_tree_add_...() functions,
20 e.g. proto_tree_add_bytes().

289 * The encoding of a field of a particular type may involve more
290 * than just whether it's big-endian or little-endian and its size.
292 * For integral values, that's it, as 99.9999999999999% of the machines
293 * out there are 2's complement binary machines with 8-bit bytes,
294 * so the protocols out there expect that and, for example, any Unisys
295 * 2200 series machines out there just have to translate between 2's
296 * complement and 1's complement (and nobody's put any IBM 709x's on
297 * any networks lately :-)).
301 * for floating-point numbers, in addition to IEEE decimal
302 * floating-point, there's also IBM System/3x0 and PDP-11/VAX
303 * floating-point - most protocols use IEEE binary, but DCE RPC
304 * can use other formats if that's what the sending host uses;
306 * for character strings, there are various character encodings
307 * (various ISO 646 sets, ISO 8859/x, various other national
308 * standards, various DOS and Windows encodings, various Mac
309 * encodings, UTF-8, UTF-16, other extensions to ASCII, EBCDIC,
312 * for absolute times, there's UNIX time_t, UNIX time_t followed
313 * by 32-bit microseconds, UNIX time_t followed by 32-bit
314 * nanoseconds, DOS date/time, Windows FILETIME, NTP time, etc..
316 * We might also, in the future, want to allow a field specifier to
317 * indicate the encoding of the field, or at least its default
318 * encoding, as most fields in most protocols always use the
319 * same encoding (although that's not true of all fields, so we
320 * still need to be able to specify that at run time).
322 * So, for now, we define ENC_BIG_ENDIAN and ENC_LITTLE_ENDIAN as
323 * bit flags, to be combined, in the future, with other information
324 * to specify the encoding in the last argument to
325 * proto_tree_add_item(), and possibly to specify in a field
326 * definition (e.g., ORed in with the type value).
328 * Currently, proto_tree_add_item() treats its last argument as a
329 * Boolean - if it's zero, the field is big-endian, and if it's non-zero,
330 * the field is little-endian - and other code in epan/proto.c does
331 * the same. We therefore define ENC_BIG_ENDIAN as 0x00000000 and
332 * ENC_LITTLE_ENDIAN as 0x80000000 - we're using the high-order bit
333 * so that we could put a field type and/or a value such as a character
334 * encoding in the lower bits.
336 #define ENC_BIG_ENDIAN 0x00000000

346 * Historically FT_TIMEs were only timespecs; the only question was whether
347 * they were stored in big- or little-endian format.
349 * For backwards compatibility, we interpret an encoding of 1 as meaning
350 * "little-endian timespec", so that passing TRUE is interpreted as that.
354 * ENC_TIME_SECS_NSECS - 8, 12, or 16 bytes. For 8 bytes, the first 4
355 * bytes are seconds and the next 4 bytes are nanoseconds; for 12 bytes,
356 * the first 8 bytes are seconds and the next 4 bytes are nanoseconds;
357 * for 16 bytes, the first 8 bytes are seconds and the next 8 bytes are
358 * nanoseconds. If the time is absolute, the seconds are seconds since
359 * the UN*X epoch (1970-01-01 00:00:00 UTC). (I.e., a UN*X struct
360 * timespec with a 4-byte or 8-byte time_t or a structure with an
361 * 8-byte time_t and an 8-byte nanoseconds field.)
363 * ENC_TIME_NTP - 8 bytes; the first 4 bytes are seconds since the NTP
364 * epoch (1901-01-01 00:00:00 GMT) and the next 4 bytes are 1/2^32's of
365 * a second since that second. (I.e., a 64-bit count of 1/2^32's of a
366 * second since the NTP epoch, with the upper 32 bits first and the
367 * lower 32 bits second, even when little-endian.)
369 * ENC_TIME_TOD - 8 bytes, as a count of microseconds since the System/3x0
370 * and z/Architecture epoch (1900-01-01 00:00:00 GMT).
372 * ENC_TIME_RTPS - 8 bytes; the first 4 bytes are seconds since the UN*X
373 * epoch and the next 4 bytes are are 1/2^32's of a second since that
374 * second. (I.e., it's the offspring of a mating between UN*X time and
375 * NTP time.) It's used by the Object Management Group's Real-Time
376 * Publish-Subscribe Wire Protocol for the Data Distribution Service.
378 * ENC_TIME_SECS_USECS - 8 bytes; the first 4 bytes are seconds and the
379 * next 4 bytes are microseconds. If the time is absolute, the seconds
380 * are seconds since the UN*X epoch. (I.e., a UN*X struct timeval with
383 * ENC_TIME_SECS - 4 to 8 bytes, representing a value in seconds.
384 * If the time is absolute, it's seconds since the UN*X epoch.
386 * ENC_TIME_MSECS - 6 to 8 bytes, representing a value in milliseconds.
387 * If the time is absolute, it's milliseconds since the UN*X epoch.
389 * ENC_TIME_SECS_NTP - 4 bytes, representing a count of seconds since
390 * the NTP epoch. (I.e., seconds since the NTP epoch.)
392 * ENC_TIME_RFC_3971 - 8 bytes, representing a count of 1/64ths of a
393 * second since the UN*X epoch; see section 5.3.1 "Timestamp Option"
396 * ENC_TIME_MSEC_NTP - 4-8 bytes, representing a count of milliseconds since
397 * the NTP epoch. (I.e., milliseconds since the NTP epoch.)
399 * The backwards-compatibility names are defined as hex numbers so that
400 * the script to generate init.lua will add them as global variables,
401 * along with the new names.

418 * Historically, the only place the representation mattered for strings
419 * was with FT_UINT_STRINGs, where we had FALSE for the string length
420 * being big-endian and TRUE for it being little-endian.
422 * We now have encoding values for the character encoding. The encoding
423 * values are encoded in all but the top bit (which is the byte-order
424 * bit, required for FT_UINT_STRING and for UCS-2 and UTF-16 strings)
425 * and the bottom bit (which we ignore for now so that programs that
426 * pass TRUE for the encoding just do ASCII). (The encodings are given
427 * directly as even numbers in hex, so that make-init-lua.pl can just
428 * turn them into numbers for use in init.lua.)
430 * We don't yet process ASCII and UTF-8 differently. Ultimately, for
431 * ASCII, all bytes with the 8th bit set should be mapped to some "this
432 * is not a valid character" code point, as ENC_ASCII should mean "this
433 * is ASCII, not some extended variant thereof". We should also map
434 * 0x00 to that as well - null-terminated and null-padded strings
435 * never have NULs in them, but counted strings might. (Either that,
436 * or the values for strings should be counted, not null-terminated.)
437 * For UTF-8, invalid UTF-8 sequences should be mapped to the same
440 * For display, perhaps we should also map control characters to the
441 * Unicode glyphs showing the name of the control character in small
442 * caps, diagonally. (Unfortunately, those only exist for C0, not C1.)
