But the old behavior is arguable not a bug. It was always expected that
the caller would check for NULL. The NULL behavior has already made it
into Solaris:
| The returned string is not translated according to the current locale,
| and strerrordesc_np() returns a NULL result for unknown error codes,
| rather than a generated descriptive string.
<https://docs.oracle.com/cd/E88353_01/html/E37843/strerrorname-np-3c.html>
So I think this ship has sailed.
By the way, I seem to recall that an incompatible version of these
functions (different from strerror_r) has been defined in POSIX and
implemented by one of the other systems. But I can't find the function
name anymore. 8-(
Thanks,
Florian
