Open a new pseudo-terminal pair. Return a pair of file descriptors
\code{(\var{master}, \var{slave})} for the pty and the tty,
respectively. For a (slightly) more portable approach, use the

\begin{funcdesc}{forkpty}{}
Fork a child process, using a new pseudo-terminal as the child's
controlling terminal. Return a pair of \code{(\var{pid}, \var{fd})},
where \var{pid} is \code{0} in the child, the new child's process id
in the parent, and \code{fd} is the file descriptor of the master end
of the pseudo-terminal. For a more portable approach, use the
\refmodule{pty} module.

Open a new pseudo-terminal pair, using \function{os.openpty()} if
possible, or emulation code for SGI and generic \UNIX{} systems.

\begin{funcdesc}{spawn}{argv\optional{, master_read\optional{, stdin_read}}}
Spawn a process, and connect its controlling terminal with the current
process's standard io. This is often used to baffle programs which
