mc/vfs

Hi!

I'm midnight commander's vfs layer. Before you start hacking me,
please read this file. I'm integral part of midnight commander, but I
try to go out and live my life myself as a shared library, too. That
means that I should try to use as little functions from midnight as
possible (so I'm tiny, nice and people like me), that I should not
pollute name space by unnecessary symbols (so I do not crash fellow
programs) and that I should have a clean interface between myself and
midnight.

Because I'm rather close to midnight, try to:

* Keep updating ChangeLog file.

* Keep the indentation as the rest of the code. Following could help
you with your friend emacs:

(defun mc-c-mode ()
"C mode with adjusted defaults for use with the Midnight commander."
(interactive)
(c-mode)
(c-set-style "K&R")
(setq c-indent-level 4
c-continued-statement-offset 4
c-brace-offset 0
c-argdecl-indent 4
c-label-offset -4
c-brace-imaginary-offset 0
c-continued-brace-offset 0
c-tab-always-indent nil
c-basic-offset 4
tab-width 8
comment-column 60))

(setq auto-mode-alist (cons '(".*/mc/.*\\.[ch]$" . mc-c-mode)
auto-mode-alist))

And because I'm trying to live life on my own as libvfs.so, try to:

* Make sure all exported symbols are defined in vfs.h and begin with
'vfs_'.

* Do not make any references from midnight into modules like tar. It
would probably pollute name space and midnight would depend on concrete
configuration of libvfs. mc_setctl() and mc_ctl() are your
friends. (And mine too :-).

PS: If you'd like to use my features in whole operating system, you
might want to link me to rpc.nfsd. On
http://atrey.karlin.mff.cuni.cz/~pavel/podfuk/podfuk.html you'll find
how to do it.

PPS: I have a friend, shared library called avfs, which is LD_PRELOAD
capable. You can reach her at http://www.inf.bme.hu/~mszeredi/avfs.
