Hi!
Our mktemp man page says:
RETURN VALUES
The mktemp() and mkdtemp() functions return a pointer to the template on
success and NULL on failure.
But POSIX[1] (and Linux) say:
The mktemp() function shall return the pointer template. If a unique name
cannot be created, template shall point to a null string.
where 'null string' is[2]
3.146 Empty String (or Null String)
A string whose first byte is a null byte
So NetBSD's mktemp returns NULL on error, while Linux returns a
pointer to string of length 0.
I think mktemp has been removed from POSIX in the meantime, but should
we switch to the POSIX behaviour?
