[R-pkg-devel] best approach to getting an external library to *not* use stdout, stderr, etc.

[Simon Barthelmé]

Hi Iñaki

Thanks for the suggestion. I'm not sure how to make it work, though, if 
you call freopen on stderr, R CMD check will still detect a call to 
stderr and trigger a warning. Have you yourself used it?

Best

Simon
