NAMEgetpt − open a new pseudoterminal master

---

LIBRARYStandard C library (libc, −lc)

---

SYNOPSIS#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <stdlib.h>int getpt(void);"

---

DESCRIPTIONgetpt() opens a new pseudoterminal device and returns a file descriptor that refers to that device. It is equivalent to opening the pseudoterminal multiplexor device open("/dev/ptmx", O_RDWR);on Linux systems, though the pseudoterminal multiplexor device is located elsewhere on some systems that use the GNU C library.

---

RETURN VALUEgetpt() returns an open file descriptor upon successful completion. Otherwise, it returns −1 and sets errno to indicate the error.

---

ERRORSgetpt() can fail with various errors described in open(2).

---

VERSIONSgetpt() is provided since glibc 2.1.

---

ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7). InterfaceAttributeValue getpt() Thread safetyMT-Safe

---

STANDARDSgetpt() is glibc-specific; use posix_openpt(3) instead.
