I have built a custom wireshark plugin on Windows but when I try to use this on an another installed wireshark version by copying the dll file, it fails to load

edit

Which function should be used instead of new_create_dissector_handle()?

The contents of the macro that was removed, i.e. create_dissector_handle()

But when I use the create_dissector_handle() function, I get the following error- epan\packet.c(3103,1): warning C4029: declared formal parameter list different from definition

Is there a workaround for this?

Yes. Update your dissector to conform to the current function argument specifications.

The dissector registration functions changed a long time ago. For some interleaving period there were the compatibility macros to ease transition, that period has ended.

To see what the functions should look like, read README.dissector in the source "doc" directory, or look at the source of any of the plugins in the source tree.
