Because POSIX states that buf is indeterminate on error, and because Corrina's patch caused a regression (ie. 1.5.18 was setting buf[0] to 0 on error). QofI states that we might as well make the indeterminate buffer useful, in case a user forgets to check the return value being NULL. -- Eric Blake -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
