[closed] dissecting tcp payload using wireshark dissector APIs in C code

hello all,

i have just the tcp payload data,i know the protocol message in the payload. what i am trying to do is calling dissector API on this packet,in my c code, expecting that it would form the proto tree that i will use in print_proto_tree function to get payload details.

i have populated the argument with required values.(except the eth,ip, related values)

but everytime i am getting this segmentation fault.

is this the correct approach.
