Dissector handle

Question

I'm trying to develop my own dissector for some protocol I've analysed. I took skeleton dissector from README.developer and filled it. Now that I'm trying to compile it I get following error, and cannot figure out what's wrong:

/home/andrey/grive/wireshark-dissector-template/packet-intl.c: In function     ‘proto_reg_handoff_intl’:
/home/andrey/grive/wireshark-dissector-template/packet-intl.c:370:58: warning: passing argument 1 of ‘new_create_dissector_handle’ from incompatible pointer type [enabled by default]

Accepted Answer

Presumably you're building from trunk, the dissector function now has four parameters which the skeleton code hasn't caught up with yet.

You'll need to append a void * to the parameter list for your dissector function, the usual format is void *data _U_. The signature of a dissector function is defined in epan\packet.h as:

typedef int (*new_dissector_t)(tvbuff_t *, packet_info *, proto_tree *, void *);
