If you're talking about oui_base_custom(), I think the better idea would be to create a field type (FT_OUI) for it.

Which OUI are we talking about? Generally speaking, a wsutil/oui_handler.? could be useful, as for instance, openSAFETY uses OUI-24 as well. So it could be made the case, to move the OUI handling outside of the dissector and into a generic wsutil or epan structure.

I don't think that's enough. The linker should be able to resolve the symbol this way, but the compiler shouldn't. Then you'd have to declare it extern. But the right thing to do is to create a .h file that holds the public declaration of the .c file, and include it. This is a best practice generally speaking, and it's whas is done in wireshark as well. Have a look at packet-dns.c/h that do what you think. Moreover, there is already a file packet-ieee80211.h: that should be the place.

Cheers,

Hi folks,

I have a need to deal with OUIs in a dissector I am writing and find
that it is defined as static void in packet_ieee80211.c.

Should I simply remove static from that declaration, or should we
promote it to some other file to make it generally available?
