ptem(4M) Streams Modules ptem(4M)
NAME
ptem - STREAMS Pseudo Terminal Emulation module
SYNOPSIS
int ioctl(fd, I_PUSH, "ptem");
DESCRIPTION
ptem is a STREAMS module that, when used in conjunction with a line
discipline and pseudo terminal driver, emulates a terminal.
The ptem module must be pushed (see I_PUSH, streamio(4I)) onto the sub‐
sidiary side of a pseudo terminal STREAM, before the ldterm(4M) module
is pushed. This is done automatically by autopush(8) on Oracle Solaris
11.4 and later releases.
On the write-side, the TCSETA, TCSETAF, TCSETAW, TCGETA, TCSETS, TC‐
SETSW, TCSETSF, TCGETS, TCSBRK, JWINSIZE, TIOCGWINSZ, and TIOCSWINSZ
termio ioctl(2) messages are processed and acknowledged. If remote
mode is not in effect, ptem handles the TIOCSTI ioctl by copying the
argument bytes into an M_DATA message and passing it back up the read
side. Regardless of the remote mode setting, ptem acknowledges the
ioctl and passes a copy of it downstream for possible further process‐
ing. A hang up (that is, stty 0) is converted to a zero length M_DATA
message and passed downstream. Termio cflags and window row and column
information are stored locally one per stream. M_DELAY messages are
discarded. All other messages are passed downstream unmodified.
On the read-side all messages are passed upstream unmodified with the
following exceptions. All M_READ and M_DELAY messages are freed in both
directions. A TCSBRK ioctl is converted to an M_BREAK message and
passed upstream and an acknowledgment is returned downstream. A TI‐
OCSIGNAL ioctl is converted into an M_PCSIG message, and passed up‐
stream and an acknowledgment is returned downstream. Finally a TIOCRE‐
MOTE ioctl is converted into an M_CTL message, acknowledged, and passed
upstream; the resulting mode is retained for use in subsequent TIOCSTI
parsing.

STREAMS Programming Guide
HISTORY
Prior to Oracle Solaris 11.4, programs needed to push the ptem module
onto the subsidiary side of a pseudo-terminal pair if open() was called
from a program not linked for XPG4 or later standards. If called from a
program linked with values-xpg4.o or values-xpg6.o, then open() would
automatically push ptem, ldterm, and ttcompat modules onto the sub‐
sidiary side, and callers pushing them as well would encounter unex‐
pected behavior.
Oracle Solaris 11.4 added these modules to /etc/iu.system.ap for
pts(4D) so that they are automatically pushed by autopush(8) regardless
of how the program is linked, and ensured that only one copy of each is
pushed onto each stream.
