On hp-ux, ioctl TIOCGPGRP always fails with errno ENOTTY (this is normal,
explained in the USG part of create_process).
I cannot find that explanation, and I am not sure what "the USG part
of create_process" refers to. Would you please show me the specific
code you mean? I'm trying to understand this. In particular,
I wonder why this code
if (!NILP (p->subtty))
err = ioctl (XFASTINT (p->subtty), TIOCGPGRP, &gid);
does not get the right value.
Does err get set to -1 when the ioctl fails?
