/**
* A pseudo-terminal
*
* A pseudo-terminal is essentially a two way pipe where one end acts as the master, and the other
* acts as the slave. The process opening the pseudo-terminal is given a handle to both ends. The
* slave end is generally given to a subprocess, possibly designating the pty as the controlling tty
* of a new session. This scheme is how, for example, an SSH daemon starts a new login shell. The
* shell is given the slave end, and the master end is presented to the SSH client.
*
* This is more powerful than controlling a process via standard in and standard out. 1) Some
* programs detect whether or not stdin/out/err refer to the controlling tty. For example, a program
* should avoid prompting for passwords unless stdin is the controlling tty. Using a pty can provide
* a controlling tty that is not necessarily controlled by a user. 2) Terminals have other
* properties and can, e.g., send signals to the foreground process group (job) by sending special
* characters. Normal characters are passed to the slave, but special characters may be interpreted
* by the terminal's <em>line discipline</em>. A rather common case is to send Ctrl-C (character
* 003). Using stdin, the subprocess simply reads 003. With a properly-configured pty and session,
* the subprocess is interrupted (sent SIGINT) instead.
*
* This class opens a pseudo-terminal and presents both ends as individual handles. The master end
* simply provides an input and output stream. These are typical byte-oriented streams, except that
* the data passes through the pty, subject to interpretation by the OS kernel. On Linux, this means
* the pty will apply the configured line discipline. Consult the host OS documentation for special
* character sequences.
*
* The slave end also provides the input and output streams, but it is uncommon to use them from the
* same process. More likely, subprocess is launched in a new session, configuring the slave as the
* controlling terminal. Thus, the slave handle provides methods for obtaining the slave pty file
* name and/or spawning a new session. Once spawned, the master end is used to control the session.
*
* Example:
*
* <pre>
* Pty pty = Pty.openpty();
* pty.getSlave().session("bash");
*
* PrintWriter writer = new PrintWriter(pty.getMaster().getOutputStream());
* writer.println("echo test");
* BufferedReader reader =
* new BufferedReader(new InputStreamReader(pty.getMaster().getInputStream()));
* System.out.println(reader.readLine());
* System.out.println(reader.readLine());
*
* pty.close();
* </pre>

/**
* A pseudo-terminal
*
* <p>
* A pseudo-terminal is essentially a two way pipe where one end acts as the parent, and the other
* acts as the child. The process opening the pseudo-terminal is given a handle to both ends. The
* child end is generally given to a subprocess, possibly designating the pty as the controlling tty
* of a new session. This scheme is how, for example, an SSH daemon starts a new login shell. The
* shell is given the child end, and the parent end is presented to the SSH client.
*
* <p>
* This is more powerful than controlling a process via standard in and standard out. 1) Some
* programs detect whether or not stdin/out/err refer to the controlling tty. For example, a program
* should avoid prompting for passwords unless stdin is the controlling tty. Using a pty can provide
* a controlling tty that is not necessarily controlled by a user. 2) Terminals have other
* properties and can, e.g., send signals to the foreground process group (job) by sending special
* characters. Normal characters are passed to the child, but special characters may be interpreted
* by the terminal's <em>line discipline</em>. A rather common case is to send Ctrl-C (character
* 003). Using stdin, the subprocess simply reads 003. With a properly-configured pty and session,
* the subprocess is interrupted (sent SIGINT) instead.
*
* <p>
* This class opens a pseudo-terminal and presents both ends as individual handles. The parent end
* simply provides an input and output stream. These are typical byte-oriented streams, except that
* the data passes through the pty, subject to interpretation by the OS kernel. On Linux, this means
* the pty will apply the configured line discipline. Consult the host OS documentation for special
* character sequences.
*
* <p>
* The child end also provides the input and output streams, but it is uncommon to use them from the
* same process. More likely, subprocess is launched in a new session, configuring the child as the
* controlling terminal. Thus, the child handle provides methods for obtaining the child pty file
* name and/or spawning a new session. Once spawned, the parent end is used to control the session.
*
* <p>
* Example:
*
* <pre>
* Pty pty = factory.openpty();
* pty.getChild().session("bash");
*
* PrintWriter writer = new PrintWriter(pty.getParent().getOutputStream());
* writer.println("echo test");
* BufferedReader reader =
* new BufferedReader(new InputStreamReader(pty.getParent().getInputStream()));
* System.out.println(reader.readLine());
* System.out.println(reader.readLine());
*
* pty.close();
* </pre>
