Yes, I was looking for the SUS API to create a pty master/slave pair, i.e.
int fd_master, fd_slave;
char *slave; ...
fd_master = open("/dev/ptmx", O_RDWR);
grantpt(fd_master);
unlockpt(fd_master);
slave = ptsname(fd_master);
fd_slave = open(slave, O_RDWR);
Now when I created the master, how to I pass the slave to a shell?
Just dup(fd_slave) for stdin, stdout, stderr and pass it to
fork()/exec()? Or do I have to use open()? Or just open once and pass
the same fd for stdin, stdout, stderr to the shell?
