* Ethereal - Network traffic analyzer
Put "extern" in front of a pile of function declarations. It makes no difference if they really are function declarations; however, in plugins, when building on OSes that don't let dynamically-loaded modules access functions in the main program (e.g., Windows), when compiling a plugin, <plugin_api.h> defines the names of those functions as (*pointer_name), so they turn into declarations of pointer variables pointing to the functions in question, and, on platforms with a def/ref model in the linker, if a plugin has more than one source file that gets linked into the plugin, the linker may get upset at two definitions of the same variable. svn path=/trunk/; revision=4114

Remove the global packet_info called "pi". Dissectors now only access their own "pinfo". A packet_info is stored in epan_dissect_t, which is created for the dissection of a single packet. GUI functions which need to access the packet_info of the currently selected packet used to use "pi"; now they use cfile.edt->pi. cfile's "edt" member is the epan_dissect_t of the currently-selected packet. The functionality of blank_packetinfo() was moved into dissect_packet(), as that's the only place that called blank_packetinfo(), after a spurious call to blank_packetinfo() was removed from packet_list_select_cb(). svn path=/trunk/; revision=4246

/* Utility routines used by packet*.c */
Instead of tweaking a "Protocol configuration options" extension header item to look more-or-less like a PPP packet, just dissect it in place and hand off to the appropriate subdissector using the PPP dissector's handoff table (which we export, along with its value_string table for protocol IDs, which we use to report the protocol ID symbolically). This means there's no point in having a configurable option to control whether to do that tweaking; make it an obsolete option. Bring "col_get_writable()" back from the dead, and have the GTP dissector save the current "writable" flag for columns, mark the columns non-writable before calling the subdissector for the PPP configuration protocol, and restore the state of the writable flag, rather than putting the columns back after the PPP configuration protocol's dissector is done. Fix some more typos in comments. Don't register the IP dissector in the "ppp.protocol" table in the GTP dissector's handoff registration routine - it's already being done in the IP dissector's handoff routine. Fix the name for CHAP to match what RFC 1994 calls it (if the name changed, it should be changed in all places, but, at least according to this message, a while ago, from Bob Sutterfield, "since the RFC defines the protocol, the RFC defines the name": http://mail-index.netbsd.org/netbsd-help/1996/05/16/0011.html and the RFC defines the name as "PPP Challenge Handshake Authentication Protocol (CHAP)"). svn path=/trunk/; revision=6617

extern gboolean col_get_writable(column_info *);
Move the pointer to the "column_info" structure in the "frame_data" structure to the "packet_info" structure; only stuff that's permanently stored with each frame should be in the "frame_data" structure, and the "column_info" structure is not guaranteed to hold the column values for that frame at all times - it was only in the "frame_data" structure so that it could be passed to dissectors, and, as all dissectors are now passed a pointer to a "packet_info" structure, it could just as well be put in the "packet_info" structure. That saves memory, by shrinking the "frame_data" structure (there's one of those per frame), and also lets us clean up the code a bit. svn path=/trunk/; revision=4370

Add the notion of a "fence" to columns. A dissector can set the fence to "protect" what's currently in the column, so that attempts to clear the column will only clear stuff after the fence and attempts to overwrite the column will append stuff after the fence. This, for example, allows a dissector to arrange that the Info column contain information for its protocol and for protocols running atop it. svn path=/trunk/; revision=7466
