Answer: not so easy and not so complicated ;-)
Currently SETEdit uses an abstraction layer called "libmigdb", that's a
separated library (currently only static version available). So you
could just write a library with the same API as "libmigdb" to
communicate with the debugger.
But this isn't the best approach. The best (and a little bit more
complicated) is to write a binary that translates "GDB/MI" commands into
the commands used by your debugger.
The GDB/MI protocol is documented in GDB docs (some missing and
missleading stuff, be careful!).
This protocol uses plain text (to avoid the problems associated with
binary data) and is designed for "Machine Interaction". It means the
format of the responses isn't designed to be human readable, but they
are quite easy to be parsed.
This approach can be done without altering SETEdit (nor libmidbg)
sources (or with very little changes). But the most important thing you
get: you can use any other gdb frontend that implements GDB/MI protocol.
I know Eclipse is one.
The "ultimate" approach is to just cooperate with the debugger team and
help to just add GDB/MI protocol to the debugger itself.
Does it answer your question? Ask me if you have doubts.
