Actually, the parsing code uses stdin (see get_input_from_stdin). For
stdout/stderr, I'm not sure.

Indeed, I would rather avoid dealing with C++ types as it makes dynamic
loading difficult (impossible?). Using FILE* was just a initial idea, to
illustrate what I had in mind.

Indeed, but if octave at least could have configurable std IO, that would
already be good. If these std IO's are then available through a well defined
API (in the same way there is an octave_stdout available), it would be
up to the oct files to use them if they want their input/output to be
handled correctly.
In the end, you have the same problem with Matlab in MEX files: if you
want something to appear in the Matlab console, you must use mexPrintf
instead of regular stdio calls (I'm talking about Matlab in GUI mode).
