I'm having trouble picking out a bit flag from a 32 bit field. Can anyone
point out where I'm going wrong?
The field is transmitted on the wire in little endian order; b0 b1 b2 b3, bits
0 - 30 are a block number and the flag I'm interested is bit 31, the top bit
of b3.
I add the item to the tree with:
proto_tree_add_item(point_tree, hf_item, tvb, offset, 4, ENC_LITTLE_ENDIAN);
and the hf def is:
{ &hf_item,
{ "A flag", "dissector.flag", FT_BOOLEAN, 32, TFS(&tfs_set_notset), 0x8000,
"A flag", HFILL }},
but when looking at the item I see the field displayed in the hex window as
"00 00 00 80", but the flag isn't set in the tree.
Similar code to the above works with 16 bit fields,
