I am working on refining a dissector and need to make sure the tree I'm
passed actually points to the field I intend. This code may be called
either before or after the packet is dissected. To do this I'm using
code like this:
if (PNODE_FINFO(tree)->hfinfo->id == hf_myproto_specialfield)
{ /* do stuff... */ }
I don't like to reach that deep into the hfinfo data structure, but it
seems that the only alternative that would work would be to call
proto_find_finfo(tree, hf_myproto_specialfield) but that's not really
what I want and incurs a much larger runtime penalty than is really
needed. Is there a better way to do this?
