Combine the GTK+ RTP Stream Analysis and RTP Graph Analysis dialogs into one. Yell at the user less. Disable the Analyze RTP Stream menu item if we don't have an RTP stream selected. There are a *lot* of moving parts in this dialog. I've tested with the few RTP captures I have but it's by no means complete. "To do" items are listed at the top of rtp_analysis.cpp. Change-Id: Id503977f069bebc46cc68bc749f0c9cbf4d37bf6 Reviewed-on: https://code.wireshark.org/review/9650 Petri-Dish: Gerald Combs <gerald@wireshark.org> Tested-by: Petri Dish Buildbot <buildbot-no-reply@wireshark.org> Reviewed-by: Gerald Combs <gerald@wireshark.org>

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

|
|
* complement and 1's complement (and nobody's put any IBM 709x's on

|
|
*
|
|
* However:
|
|
*
|
|
* for floating-point numbers, in addition to IEEE decimal
|
|
* floating-point, there's also IBM System/3x0 and PDP-11/VAX
|
|
* floating-point - most protocols use IEEE binary, but DCE RPC
|
|
* can use other formats if that's what the sending host uses;
|
|
*
|
|
* for character strings, there are various character encodings
|
|
* (various ISO 646 sets, ISO 8859/x, various other national
|
|
* standards, various DOS and Windows encodings, various Mac
|
|
* encodings, UTF-8, UTF-16, other extensions to ASCII, EBCDIC,
|
|
* etc.);
|
|
*
|
|
* for absolute times, there's UNIX time_t, UNIX time_t followed
|
|
* by 32-bit microseconds, UNIX time_t followed by 32-bit
|
|
* nanoseconds, DOS date/time, Windows FILETIME, NTP time, etc..
|
|
*
|
|
* We might also, in the future, want to allow a field specifier to
|
|
* indicate the encoding of the field, or at least its default
|
|
* encoding, as most fields in most protocols always use the
|
|
* same encoding (although that's not true of all fields, so we
|
|
* still need to be able to specify that at run time).
|
|
*
|
|
* So, for now, we define ENC_BIG_ENDIAN and ENC_LITTLE_ENDIAN as
|
|
* bit flags, to be combined, in the future, with other information
|
|
* to specify the encoding in the last argument to
|
|
* proto_tree_add_item(), and possibly to specify in a field
|
|
* definition (e.g., ORed in with the type value).
|
|
*
|
|
* Currently, proto_tree_add_item() treats its last argument as a
|
|
* Boolean - if it's zero, the field is big-endian, and if it's non-zero,
|
|
* the field is little-endian - and other code in epan/proto.c does
|
|
* the same. We therefore define ENC_BIG_ENDIAN as 0x00000000 and
|
|
* ENC_LITTLE_ENDIAN as 0x80000000 - we're using the high-order bit
|
|
* so that we could put a field type and/or a value such as a character
|

* encoding in the lower bits.
