Wireshark · Wireshark-dev: Re: [Wireshark-dev] Add the next Tvb packet to current tvb before dissecting

[wsgd <wsgd@xxxxxxx>]

Hello,

The displayed error says that tvb_set_child_real_data_tvbuff returns 
void (nothing).
See epan/tvbuff.h
So you are trying : next_tvb=void


Other thing :
I do not understand why you are trying to do reassembly by yourself 
since this is the goal of tcp_dissect_pdus.
