1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withGuy Harris1-2/+8
dynamically-assigned "ett_" integer values, assigned by "proto_register_subtree_array()"; this: obviates the need to update "packet.h" whenever you add a new subtree type - you only have to add a call to "proto_register_subtree_array()" to a "register" routine and an array of pointers to "ett_", if they're not already there, and add a pointer to the new "ett_" variable to the array, if they are there; would allow run-time-loaded dissectors to allocate subtree types when they're loaded. svn path=/trunk/; revision=1043

1999-10-12New proto_tree header_field_info stuff. Header_field_infos now containGilbert Ramirez1-3/+5
the base for numbers to be displayed in, bitmasks for bitfields, and blurbs (which are one or two sentences describing the field). proto_tree_add*() routines now automatically handle bitfields. You tell it which header field you are adding, and just pass it the value of the entire field, and the proto_tree routines will do the masking and shifting for you. This means that bitfields are more naturally filtered via dfilter now. Added Phil Techau's support for signed integers in dfilters/proto_tree. Added the beginning of the SNA dissector. It's not complete, but I'm committing it now because it has example after example of how to use bitfields with the new header_field_info struct and proto_tree routines. It was the impetus to change how header_field_info works. svn path=/trunk/; revision=815
1999-10-09Add display filters.Laurent Deniel1-22/+31
svn path=/trunk/; revision=794
1999-09-17Add a "BYTES_ARE_IN_FRAME()" macro, to test whether there are aGuy Harris1-4/+4
specified number of bytes of captured data in the frame at the specified offset, and a "IS_DATA_IN_FRAME()" macro, to test whether there are any bytes of captured data in the frame at the specified offset, and convert some bounds checks to use them. Add a dissector for the Internet Printing Protocol. svn path=/trunk/; revision=685
1999-08-26Convert a bunch of uses of "fd->cap_len" to use "pi.captured_len" (or toGuy Harris1-4/+4
use END_OF_FRAME), so that they don't look at stuff in an IP datagram past the end of the IP datagram (i.e., frame padding). svn path=/trunk/; revision=584
1999-07-29Made the protocol (but not the fields) use the new proto_tree routine,Gilbert Ramirez1-4/+16
allowing users to filter on the existence of these protocols. I also added packet-clip.c to the Nmake makefile. svn path=/trunk/; revision=402
1999-07-07Created a new protocol tree implementation and a new display filterGilbert Ramirez1-41/+40
mechanism that is built into ethereal. Wiretap is now used to read all file formats. Libpcap is used only for capturing. svn path=/trunk/; revision=342
1999-03-23Removed all references to gtk objects from packet*.[ch] files. They nowGilbert Ramirez1-50/+47
reference the protocol tree with struct proto_tree and struct proto_item objects. That way, the packet decoding source code file can be used with non-gtk packet decoders, like a curses-based ethereal, e.g. I also re-arranged some of the information in packet.h to more appropriate places (like other packet-*.[ch] files). svn path=/trunk/; revision=223
