about VSTa coding (name clash with Posix) and ext2fs

Hello all,

At home, i'm trying to port Linux ext2 filesystem to VSTa (by writing
an ext2fs filesystem server). I'm using the e2fsprogs-0.5b and coding
above its libext2. I'm actually developping under linux and cross-compiling
(with gcc2.5.2 and binutils 2.5.2 targeted for VSTa) to VSta.

A: I do have some remarks about VSTa coding:
--------------------------------------------

1. the errno EINTR EIO E* etc stuff is nearly a nightmare. In
<sys/fs.h> errors are strings -this is a good idea. But EINTR is
defined as a string in <sys/fs.h> and as a Posixly number in
<errno.h>. I believe that this is annoying. I suggest that EINTR in
<sys/fs.h> should be ERRINTR (or even VSTA_ERRINTR) and defined as a
string, living EINTR only in libc for Posixy camouflage. Also, for
easier internationalization it should still be an indentifier like
string (ie "ERR:INTERRUPT" instead of "got an interrupt") -i don't
have at work the exact values but you see what i mean -someday we
should be able to give the user an error message in his native
language -eg "Interrompu" in French instead of "Interrupted".

2. Also the S_ISDIR macro (and similars) and S_IFDIR value should in
my humble opinion only appear in <unistd.h> since they are only for
Libc.

3. ino_t should be typedef-ed in <sys/types.h>.

B. my ext2fs file server.
-------------------------

Also, i might once have my ext2fs in alpha state (i don't promise
anything; i might also give up); currently i did handle correctly
some FS_STAT requests. Is there somebody interrested in alpha testing?
If yes, please email me.

I do lack some tiny documentation about the filesystem protocols. I
figured out some of them. I don't really understand what the FS_FID
request is for. I don't have a really clear picture of what a client
connection to a file server is exactly. Basically, i copied the
dos_main routine of the dos fs and hacked it.

If no one have any documentation about the filesystem protocol, i
might end writing one but i need someone to proofread and correct me.

All VSTa-ling and Linux-ing is done at home only so some names, ids,
etc might be wrong.

Also, i didn't recieve anything of the VSTa mailing list since more
than a week. Is it normal?
