Accessing binary data

[ohm314]

Hello!

First off, thanks for the great work! sharktools is proving very useful to me!
I'm using pyshark to filter/dissect some telecom protocols. I've come across a problem that in one case a field is not directly exposed by libwireshark (a tag that signifies in what state a TCAP dialogue is). In wireshark itself I can inspect the binary data and see that the first byte of the tcap segment contains this value, however I couldn't find a obvious way to do this using pyshark. For now I hacked sharktools_core.c to return a string representation of the hexdump instead of the field_name for this case. Can this be done maybe cleaner, through a bit of API? I have just started working both with wireshark and python .so modules but I gladly help with some direction :)
Thanks in advance.

cheers
