Don't know how remote debugging programs like gdb or something work with this, but a naive and
the more annoying-to-write approach could be a socket on the other side which receives commands.
There are passed through a function that selects the debugging functions by identifiers (strings
would be best, I think). Depending on what is possible with the current debugger, parameter(s) are
required (pointers? names?) and a way to obtain them from the debugger over there (this could be
the only addition to the debugger process interface). The socket over there writes back the data
so that the IDE here can display the stuff as if it was received from the debugger... This is a
technically not that complicated protocol, I think. Quickly googled, the gdb seems to have
implemented a GDB remote protocol, too - what else?
