Ethereal-dev: Re: [Ethereal-dev] how to access a global variable defined inwiretap(new format)
Actually I feel the other way. Even if it is the trace file property, I wouldnt want to use a global variable.
You could have a static global variable that is set in your wiretap _open() function. And on each call to your wiretap _seek_read() you could set the pseudo_header->endian_type value to the global variable. Just one additional assignment for each packet.
I still feel passing through the pseudo_header is a good way!! :)

Peudo_header means we are passign information for
every packet whereas say for example we just want to pass whether packet are in
big/little format or some specific information which is applicable to whole
trace (all the packets). passing infomation in Pseudo_header is not gud option
in such type of cases.

The best way in my opinion will be to pass such
infromation through the pseudo_header defined for your format.
Will
this be an entire trace file specific property or one that varies for each
packet in the file?
Thanks,

hi
I have written a new capture format(dec-trace)
which reads from saved file & corresponding dissector.
Since dec-trace can be in either of big/little
format. so i want to pass this global variable from wiretap (where it will
read endian type) to epan/dissector (where value of this variable will
be read by dissector & based on that decoding will take
place).
It was workign on linux platform very
well,
but as i building the same on Windows platform
using msvc it is showing linking problem. unresolved reference.
/******************** I m not sure but this
could be the reason ***********/
When i tried to go in deep it could be b'cos of
dissector.lib. since linker tries to resolves it within dissector.lib.
/**************************************************************************************/
what could be the way access global variable
defined in wiretap ?

Raman
