Описание (Description)

getpt() 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.
