Wireshark-dev: [Wireshark-dev] Query about TCP reassembly

Hi,
 
I have a protocol (lets call it "myproto") that runs atop TCP, and myproto messages are coming split across multiple TCP segments.
I have to reassemble myproto messages, that are variable in size.
 
myproto message header does not contain any length information about the total size of myproto message.
From the myproto message header I can only know if it is the last message fragment or there is more fragment to follow.
I have to reassemble myproto message fragments till I get a fragment that says it is the last one.
 
Can I use tcp_dissect_pdus() in this case?
If yes, how ?
If no, what is the way to reassemble such a protocol.
 
Thanks,
Munish
