Re: Equivalence table between C++ and C file open modes

There's also ios::app alone (soon to be added to issue 596) which

I know something is still in flux, I read your message on the reflector. The table is just an adaptation of the existing Table 92 (+ the mentioned addition), which is about basic_filebuf, not fstream or something else. AFAIK, it reflects exactly the behavior which we are implementing, or at least it should: in basic_file_stdio.cc, fopen_mode returns zero, meaning error, if anything else is passed.
