Here is what I do (now) - I'm on Linux:
- cd epan/dissectors/
- Pick a letter from the alphabet.
- grep emem.h packet-<letter>*.c
- ../../tools/checkAPI.pl -g emem packet-<letter>*.c
- Fix inconsistencies (remove includes for emem.h from files that don't
use ep_ or se_ functions, add the include where it is missing
- Go through all files that only contain "simple to convert" functions
+ Replace the include statement and se_ and ep_ functions the way Evan
described, then compile and install libwireshark (I do:
"make -C epan install)
+ run "tshark -v" to find obvious breakages. If it breaks, "svn revert"
the file
+ Next file
- Commit my changes
Maybe you can do this and once you have successfully converted the fist
file open a bug and attach your patch to it. Depending on the feedback
go over the patch again or (once sufficiently confident) finish all
dissectors for that letter and attach the patch to the previous bug again.
Ciao

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
