The explain_tmpnam_on_error function is used to call the tmpnam(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tmpnam(3) function, but still returns to the caller.

pathname
    The pathname, exactly as to be passed to the tmpnam(3) system call.

RETURN VALUE
The explain_tmpnam_or_die function only returns on success, see tmpnam(3) for more information. On failure, prints an explanation and exits, it does not return.

The explain_tmpnam_on_error function always returns the value return by the wrapped tmpnam(3) system call.
