Hello, I just looked through screen's source code and I saw that it tries almost any way to open up a PTY, except for the only way described in POSIX, namely posix_openpt():
http://www.opengroup.org/onlinepubs/000095399/functions/posix_openpt.html
We can just call posix_openpt() and ptsname() to obtain a PTY and figure
out its name.
I've attached a really simple patch to fix screen to use posix_openpt(),
but I didn't add the autoconf parts, because for some reason, it gave a
lot of strange errors on my box. We can only use this code if
posix_openpt() and ptsname() are available. If someone else is willing
to add those bits for me, that would be great.
Yours,
