Dear Joerg and Evan,

Can any of you brief me about what should be done. I would like to get involved and learn.

thanks :)

sincerely,

Kaushik.

Unfortunately emem.h is included everywhere via packet.h via
packet_info.h via address.h, so there are dissectors that use it
without including it directly. check-APIs is more reliable since it
actually looks for the function calls.

Put the following in your vimrc:
let @e = 'xxiwmem^[/(^Mawmem_packet_scope(), ^[/\<ep_^Mkj'
let @s = 'xxiwmem^[/(^Mawmem_file_scope(), ^[/\<se_^Mkj'

Then the 'e' macro will convert an ep_* call and jump to the next one,
the 's' macro will convert an se_* call and jump to the next one.
These only work for functions like _alloc and _strdup, for
data-structures (like ep_strbuf_append) which take the data-structure
and not the scope as the first argument you will have to convert
manually still, but there are not many of those.

The doc/README.wmem section 2.1.1 includes a brief example of how
calls can be replaced. You can also take a look at some of my (and
Joerg's) previous commits doing conversion.
