Here is the bash-3.1 code from general.c for check_dev_tty.
It is invoked shortly after main...
void
check_dev_tty ()
{
int tty_fd;
char *tty;
tty_fd = open ("/dev/tty", O_RDWR|O_NONBLOCK);
if (tty_fd < 0)
{
tty = (char *)ttyname (fileno (stdin));
if (tty == 0)
return;
tty_fd = open (tty, O_RDWR|O_NONBLOCK);
}
close (tty_fd);
}
It seems to open and close /dev/tty and return nothing.
This seems very strange to me.
Why is it doing this?
