NAME

       getpt - open the pseudo-terminal master (PTM)

SYNOPSIS

       #include <stdlib.h>

       int getpt(void)

DESCRIPTION

       getpt() opens a pseudo-terminal master and returns its file descriptor.
       It is equivalent to open("/dev/ptmx",O_RDWR|O_NOCTTY) on Linux systems,
       though  the pseudo-terminal master is located elsewhere on some systems
       that use GNU Libc.

RETURN VALUE

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

CONFORMING TO

       getpt() is specific to GNU Libc.
