• ISATTY(3P) man-page

ttyname

public static String ttyname(int filedes)

openpty

public static int openpty(int[] amaster,
 int[] aslave,
 byte[] name,
 CLibrary.Termios termios,
 CLibrary.WinSize winsize)

The openpty() function finds an available pseudoterminal and returns file descriptors for the master and slave in amaster and aslave.

Parameters:

amaster - master return value

aslave - slave return value

name - filename return value

termios - optional pty attributes

winsize - optional size

Returns:

0 on success
