Hi everybody
I have a payload that its size is 42 bits. I am getting it from the TVB
in little Endian.
I have no problem displaying the whole payload as big endian with a
guint 64bit variable:
guint32 f2_val1, f2_val2;
guint64 f2_val;
f2_val1 = tvb_get_letohl(tvb, *plen)
f2_val2 = tvb_get_letohl(tvb, (*plen+4));
f2_val = f2_val1;
f2_val= (f2_val<<32);
f2_val = f2_val|f2_val2;
Are threr any suggestions what can I use to display it correctly. As I
have seen that "proto_tree_add_bits_ret_val", although having a "big
endian/little endian" operand, that "little endian" is not implemented
yet.
If you have a big endian number, than the high part should be *plen, the
lower part (*plen)+4 not (*plen+4). The latter is plen[4].
suggestions:
- Check the (*plen+4) term.
- Check that your 32 bit variables have the expected values.
- Check your variable names ;-) I got confused while trying to reproduce
it since with the names f2_val and f2_val2. If the code above is not
literally from your dissector but "simplified" you probably also have
done this failure.
