Here's a paraphrase of the code that takes care of setting up the
child's terminal (error checking omitted). Anyone got an idea what
I'm missing?
pid = fork();
...
if(pid == 0) {
close(pty); /* master */
close(0);
close(1);
close(2);
pgrp = setsid();
tty = open(..., O_RDWI | O_NOCTTY); /* pty slave */
#ifdef TIOCSTTY
rc = ioctl(tty, TIOCSCTTY, (char*)0);
#endif
#ifdef SVR4
ioctl(tty, I_PUSH, "ptem");
ioctl(tty, I_PUSH, "ldterm");
ioctl(tty, I_PUSH, "ttcompat");
#endif
dup2(tty, 0);
dup2(tty, 1);
dup2(tty, 2);
if(tty > 2) close(tty);
execvp(...)
} else {
/* nothing interesting */
}
