The prefix, exactly as to be passed to the tempnam(3) system call.
Return Value
The explain_tempnam_or_die function only returns on success, see tempnam(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_tempnam_on_error function always returns the value return by the wrapped tempnam(3) system call.
