Hello,
I use code below for checking if the plugin is running with
the same version which it has been compiled with.
Regards,
Tomas

Hello,
with recent
Wireshark SVN versions, my TCP plugins which use re-assembly are throwing
exceptions.
The
corresponding documentation in README.developer should change too to reflect
that.
In 2.7.1 Using
tcp_dissect_pdus(), the text should read:
-----------------------------------
a
routine that takes as arguments a packet_info pointer, a tvbuff
pointer and an offset
value representing the offset into the tvbuff at
which a PDU
begins and should return - *without* throwing an exception
(it
is guaranteed that the number of bytes specified by the
previous
argument to tcp_dissect_pdus is available, but more data
might
not be available, so don't refer to any data past that) -
the
total length of the PDU, in bytes;
-----------------------------------
I updated my plugins
and it seems to be OK.
The ideal would be
to protect
the plugins from being incompatible from one Wireshark version to another (I
know binary compatibility is not guaranteed, but I would like to make this as
transparent as possible).
The first idea that
comes to me is having access to the SVN release at run time (compile time is not
enough as we provide plugin binaries) and test against this.
But maybe there is
something that already exist for that?
Thanks,
Olivier.
