Function nix::pty::openpty

pub fn openpty<'a, 'b, T: Into<Option<&'a Winsize>>, U: Into<Option<&'b Termios>>>(
    winsize: T, 
    termios: U
) -> Result<OpenptyResult>

Create a new pseudoterminal, returning the slave and master file descriptors in OpenptyResult (see openpty).

If winsize is not None, the window size of the slave will be set to the values in winsize. If termios is not None, the pseudoterminal’s terminal settings of the slave will be set to the values in termios.
