Get rid of WTAP_ENCAP_NONE; replace it with WTAP_ENCAP_UNKNOWN, which
means "I can't handle that file, it's using an encapsulation I don't
support".
Check for encapsulations we don't support, and return an error (as is
already done in "libpcap.c").
Check for too-large packet sizes, and return an error (as is already
done in "libpcap.c").
Print unsigned quantities in Wiretap messages with "%u", not "%d".

return 1 on success, -1 if they got an error, and 0 if the file isn't of
the type that file is checking for, and supply an error code if they
return -1; have "wtap_open_offline()" use that error code. Also, have
the per-capture-file-type open routines treat errors accessing the file
as errors, and return -1, rather than just returning 0 so that we try
another file type.
Have the per-capture-file-type read routines "wtap_loop()" calls return
-1 and supply an error code on error (and not, as they did in some
cases, call "g_error()" and abort), and have "wtap_loop()", if the read
routine returned an error, return FALSE (and pass an error-code-pointer
argument onto the read routines, so they fill it in), and return TRUE on
success.
Add some new error codes for them to return.
Now that "wtap_loop()" can return a success/failure indication and an
error code, in "read_cap_file()" put up a message box if we get an error
reading the file, and return the error code.
Handle the additional errors we can get when opening a capture file.
If the attempt to open a capture file succeeds, but the attempt to read
it fails, don't treat that as a complete failure - we may have managed
to read some of the capture file, and we should display what we managed
to read.

write them in "libpcap" format, but the mechanism can have other formats
added.
When creating the temporary file for a capture, use "create_tempfile()",
to close a security hole opened by the fact that "tempnam()" creates a
temporary file, but doesn't open it, and we open the file with the name
it gives us - somebody could remove the file and plant a link to some
file, and, if as may well be the case when Ethereal is capturing
packets, it's running as "root", that means we write a capture on top of
that file.... (The aforementioned changes to Wiretap let you open a
capture file for writing given an file descriptor, "fdopen()"-style,
which this change requires.)

but does not link. Perhaps someone who understands the MS tools can help
out. I made it link a few months ago, but with different version of glib/gtk+.
I can't remember how I made it link.
Most of the compatibility issues were resolved with adding
#ifdef HAVE_UNISTD_H the the source code. Please be sure to add this to all
future code.

supplied by Tim Farley.
Tim also indicated that the Network Monitor network types may be NDIS
network types+1. It also appears that NetXRay/Windows Sniffer network
types may be NDIS network types as well.

(presumably a Windows version).
Note also that version 2.001 files appear to have microsecond time
stamps, like version 1.1 files.
svn path=/trunk/; revision=228
This assumes that the time stamps are still in units of microseconds; I
don't yet have a text decode of the version-2.001 file from the program
that decoded it, so I can't check the time stamps.

appears to be the UNIX "time_t" when the capture started, so use that to
figure out the time when a packet was captured.

by Network General (subsequently merged with McAfee Associates into
Network Associates), called "Sniffer Basic".
A similar format appears to be used by the Windows Sniffer Pro.
