Ahh thank you, i think i get that. But also, for "id". It takes an int, but what if i want to put a different string there? I want to be able to include my own string for output that isn't in a static const value_string. I will be return data from a function from a loaded dll. And just something like:
proto_tree_add_uint(tree, "Test: ", tvb, 0, 0, 7)
or
proto_tree_add_uint(tree, testfunction(), tvb, 0, 0, 7)
where testfunction() would return a char * or something of the sort. Is there an easy way to do something like this?

Hi,
Use as tvb the tvb you got when the dissector was called and the start and
length of the data you feed to the external code. Or just use 0 for both.
These values are only used for marking the relevant bytes in the packet bytes
pane (usually the lower pane). Note that the tvb is mandatory, it can't be NULL.
Thanx,
Jaap
