Wat (wie) is pseudo-tty - definitie

PAIR OF PSEUDO-DEVICES

Pseudo TTY; Pseudo-TTY; Pseudo terminal

pseudo-tty

Berkeley Unix networking device which appears to an application program as an ordinary terminal but which is in fact connected via the network to a process running on a different host or a windowing system. Pseudo-ttys have a slave half and a control half. The slave tty (/dev/ttyp*) is the device that user programs use and the control tty (/dev/ptyp*) is used by daemons to talk to the net. (1994-11-08)

Pseudoterminal

In some operating systems, including Unix and Linux, a pseudoterminal, pseudotty, or PTY is a pair of pseudo-device endpoints (files) which establish asynchronous, bidirectional communication (IPC) channel (with two ports) between two or more processes. The master provides means by which a terminal emulator process controls the slave.

GREEK PREFIX: FALSE

Psuedo; Pseudo

Pseudo- is used to form adjectives and nouns that indicate that something is not the thing it is claimed to be. For example, if you describe a country as a pseudo-democracy, you mean that it is not really a democracy, although its government claims that it is.

Pseudoterminal

In some operating systems, including Unix and Linux, a pseudoterminal, pseudotty, or PTY is a pair of pseudo-device endpoints (files) which establish asynchronous, bidirectional communication (IPC) channel (with two ports) between two or more processes. The master provides means by which a terminal emulator process controls the slave. The slave, emulates a hardware text terminal device. PTY are similar to bidirectional pipes.

The master files are typically used by networking applications (e.g. rlogin) and slave files are used by terminal-oriented programs such as shells (e.g. bash) as a processes to read/write data back from/to master endpoint. Common application of PTYs is in providing network login services.

Devpts is a Linux Kernel virtual file system used to emulate PTYs connection.

Linux implementation is based on System V-style terminals (commonly referred as UNIX 98 pseudoterminals) and provides POSIX and the Single Unix Specification API in the form of a posix_openpt() function since 1998.

Unix tty command is typically used to get PTY file path connected to the current standard input.
