I also don't like the fact that the error codes aren't the standard errno E* constants, but we already had this debate once. :-) (As with threading, it is my opinion that Posix should be acknowledged.)
The intent _is_ to supply the actual system error code (errno for POSIX). There is another function available to convert to a portable code if desired.
My point was that errno should be the portable error code. This will save you one mapping. Your arguments for not using E* were purely implementation-driven and at this stage of the library development it makes sense to revisit the issue from standardization point of view.
I agree that it is time to re-visit these issues and they are going to apply to more than just the Filesystem library. I don't believe The E* names are portable to non-posix systems which includes ( at least part of ) Windows. I think that by default, C++ libraries should return C++ error names and not POSIX or any other platform or native error names. There should probably be a convention for mapping between exception names and error names. This will ease the programmers task as the move between platforms. just my 2p worth. /ikh _______________________________________________________________________ This email has been scanned for all known viruses by the MessageLabs Email Security System. _______________________________________________________________________
