I got the C wrapper working. As it turns out, it's enough to attach
stdout to the pty slave. . I havn't the faintest idea where stderr goes,
but sudo seems happy.

It's  ~ 100 lines of C code, most of which copied from an old utility I
made some years ago. Not to bad IMHO. Thanks again for all help!


PS: if there is any interest in that code, just let me know. It's 
public, for sure.
