well as in records in the file. Change the error message
wtap_strerror() returns for it to reflect that.
Use it for some file header problems for which it wasn't already being
used - WTAP_ERR_UNSUPPORTED shouldn't be used for that, it should only
be used for files that we have no reason to believe are invalid but that
have a version number we don't know about or some other
non-link-layer-encapsulation-type value we don't know about.

format requires seeking when writing it". Change the "can compress"
Boolean in the file format table to "writing requires seeking", give all
the entries the proper value, and do the checks for attempting to write
a file format to a pipe or write it in compressed format to common code.
This means we don't need to pass the "can't seek" flag to the dump open
routines.

file_read(buf, bsize, count, file) macro is compilant with fread
function and takes elements count+ size of each element, however to make
it compilant with gzread() it always returns number of bytes.
In wiretap file_read() this is not really used, file_read is called
either with bsize set to 1 or count to 1.
Attached patch remove bsize argument from macro.

point, so we don't have issues with numbers not being exactly
representable; that makes it less likely that the change described below
will change a time stamp if it's not fixing the time stamp (i.e., if
time_day is 0).
The Sniffer manual "Expert Sniffer(R) Network Analyzer Operations,
Release 5.50" says that a frame2_rec has a time stamp with an 8-bit
time_high field and an 8-bit time_day field. Interpreting the time
stamp that way fixes the time stamps in at least some captures; see, for
example, bug 2251.

I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ...
What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere.
As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon.
Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way...
As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number...

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors. Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.
Add messages for cases where those errors were returned without printing
an additional message.
Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.
Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument. (That handles a lot of the work of putting the info
string into the error message.)
Make some variables in "ascend-grammar.y" static.
Check the return value of "erf_read_header()" in "erf_seek_read()".
Get rid of an unused #define in "i4btrace.c".

0 means "there is no FCS in the packet data", 4 means "there is an FCS
in the packet data", -1 means "I don't know whether there's an FCS in
the packet data, guess based on the packet size".
Assume that Ethernet encapsulated inside other protocols has no FCS, by
having the "eth" dissector assume that (and not check for an Ethernet
pseudo-header).
Have "ethertype()" take an argument giving the FCS size; pass 0 when
appropriate.
Fix up Wiretap routines to set the pseudo-header. This means we no
longer use the "generic" seek-and-read routine, so get rid of it.

as it's the major version number.
Try using the first word of "rsvd" to determine whether a capture is an
ISDN capture or not in version 1 captures.
Version 1 captures look as if they might also have a REC_HEADER2 record
- it's longer than the ones in version 4 and 5 captures, but it still
appears to have a network subtype in the 5th byte.
Get rid of the heuristic that checks for WTAP_ENCAP_ISDN by looking at
the packet data; if we fail to recognize an ISDN capture, we should look
for stuff in the headers to determine whether the capture is one or not.

Sniffer format, it doesn't distinguish between LE Control and LANE
encapsulated LAN frames, so we can't rely on the ATM subtype being
correct even when reading DOS Sniffer captures - we force it to

HDLC-flavored encapsulation (or, at least, it was in at least one
capture). Instead, treat it as WTAP_ENCAP_PER_PACKET, and infer the
packet type, as we do for NET_ROUTER.
For NET_ROUTER captures, if the ISDN channel number is zero, infer the
packet type from the contents, rather than wiring it to PPP - it might
be, for example, Cisco or Wellfleet HDLC.
Fix the check for Cisco HDLC to look for 0x0F 0x00 and 0x8F 0x00, as
0x0F, not 0x08, is the unicast address in Cisco HDLC.
When fixing the pseudo-header, fix it for WTAP_ENCAP_WFLEET_HDLC,
WTAP_ENCAP_CHDLC, and WTAP_ENCAP_PPP_WITH_PHDR, as well as for
WTAP_ENCAP_ISDN, as the three ones listed don't use x25.flags, they use
p2p.sent.
