Описание (Description)
getpt() opens a new pseudoterminal device and returns a file
descriptor that refers to that device. It is equivalent to

on Linux systems, though the pseudoterminal multiplexor device is
located elsewhere on some systems that use the GNU C library.
Возвращаемое значение (Return value)
getpt() returns an open file descriptor upon successful
completion. Otherwise, it returns -1 and sets errno to indicate
the error.
Ошибки (Error)
getpt() can fail with various errors described in open(2).
