Hi Ryan,
Welcome to Barry!
I just got a chance to look at your code in detail today, and thanks
very much. I like to see people using Barry in ways I didn't expect
originally. :-)
This would ideally be a record parser in the Barry library, and since
you've already done the reverse engineering and proof of concept, it's
just a matter of doing the porting.
I notice that your code is licensed under GPL v3. Barry is licensed
under "GPL v2 and any later version". As a library, this makes it
compatible with a slightly wider number of application licenses. But it also
means that we can't include your code directly into the library without
changing our license as well. I could drop your code in the contrib/
directory though. Would you be willing to relicense your code and
documentation under GPL v2 and later?
If so, I'd like to apply your bb_sms_format.txt file as a documentation
patch right away, and we can work together on porting the record parsing
code to the Barry library.

Here's a little feedback from reading the code:
- I see you make use of custom bit stream code, and then
parse the streams using a series of if statements.
The way Barry does parsing like this is to use a set of
structs that match the data layout as closely as possible.
This is a challenge sometimes, but a series of if statements
should translate fairly well into a struct.
- you have custom code to convert from UCS2 to UTF8 manually...
in Barry, we use the iconv library, and we have a class wrapper
to do the work... this conversion is optional and
configurable in Barry as well... see the IConverter class
- some of the manual memory handling should probably be changed to
std::string or Barry's Data class
That said, I've run the code, and it works as advertised. :-)
Thanks again,
- Chris
