Hi,
new_octet_aligned_subset_bits() in packet-per.c may be what you want.
If so perhaps it should be made a tvbuff function.
Best regards

Ämne: [Wireshark-dev] Create a new tvb from a bit offset in the currenttvb

Hello,

does anyone know if there is code or an api call in Wireshark
that will allow me to create a new tvb subset a la

tvb_new_subset()

but from a bit offset?

I want to create a subset of a certain length in octets starting
with the last 3 bits of the octet I'm currently processing.

Example:

create subset of 50 octets from the 20th octet and 5th bit of
my current tvb 

Thanks in advance!
