Summary: ttyname_r failing isatty always returns ENOTTY instead
of the actual error
Product: Base System
Version: 11.0-CURRENT

Here's the bug I was trying to find with bug 191931 with ttyname_r (it always
assumes that isatty failing means ENOTTY):
66 /* Must be a terminal. */
67 if (!isatty(fd))
68 return (ENOTTY);
It's always assuming that isatty failing means ENOTTY:
