Thomas, Simon,
Thank you for your answers. I will have a look at the code Thomas gave
me and probably also have another look at src/unix/sys-std.c. I'll get
back when I have this working, or, more likely, when I can't get this
to work.
As for the example code. I know it is very fragile. I tried to make a
minimal complete example that showed the problem without having to
attach hundreds of lines of code that nobody will read. However, what
parts are unix specific? Is it the int Rf_initialize_R and
R_running_as_main_program? What non os specific options do I have?
Again thank you for your answers.
Regards,
Jan
