ttyname.c

[Joel Sherrill]

Hi,

With RTEMS, we build newlib before the OS.  We do not have
access to termios yet.  So the new ttyname.c does not compile
for RTEMS inside newlib.   Would it be OK to use isatty()
instead of this?

  /* Must be a terminal. */
  if (tcgetattr (fd, &tty) < 0)
    return errno;       /* Can be EBADF or ENOTTY */

newlib already assumes isatty() exists.

Attached is a patch.

    * libc/unix/ttyname.c: Use isatty() instead of tcgetattr().
