I have spent some time looking over the code you mention. Is the main difficulty figuring out how to deal with the signal handlers so that Ctrl-C is properly handled?

The rpy2 version in the tip on bitbucket has an attempt at having it... but I wrote it in a hurry, and without a Windows box to compile it on - it is most certainly not working, and most likely not even compiling under win32 (no problem on UNIX-alikes). > > I looked through the code and understand basically how it works.

I can't tell if the reason is good, but it seemed to me that R's configure step on win32 does not define R_INTERFACE_PTRS (but I am ready to hear that I am completely mistaken). > Is there some reason why the code won't work on win32? > The true reason lies at the C level.
