ОПИСАНИЕ

       ctermid() returns a string which is the pathname for the current
       controlling terminal for this process.  If s is NULL, a static
       buffer is used, otherwise s points to a buffer used to hold the
       terminal pathname.  The symbolic constant L_ctermid is the
       maximum number of characters in the returned pathname.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       The returned pathname may not uniquely identify the controlling
       terminal; it may, for example, be /dev/tty.

       It is not assured that the program can open the terminal.
