| 14 | <P>Besides the example DOS file system that comes with the BeOS developers
|
|---|
| 15 | stuff, there's also a CD-ROM file system example. If you installed the
|
|---|
| 16 | optional stuff on the BeOS 5.0 Pro CD-ROM (or the developer's kit from the free
|
|---|
| 17 | site), it's at: /boot/optional/sample-code/add-ons/iso9660
|
|---|
| 18 |
|
|---|
| 19 | <P>On <A HREF="http://www.bebits.com/">BeBits</A> you can get source code
|
|---|
| 20 | examples from a few programs, such as AtheOS FS (<A
|
|---|
| 21 | HREF="http://www.bebits.com/app/2028">app 2028 on BeBits</A>). There used to
|
|---|
| 22 | be a copy of NTFS too with source (<A HREF="http://www.bebits.com/app/620">app
|
|---|
| 23 | 620 on BeBits</A>), but the site seems to be down. There are also other file
|
|---|
| 24 | systems there, but source is not included (some have it available on request).
|
|---|
| 25 |
|
|---|
| 26 | <P>Another useful source of information is the BeOS developer library
|
|---|
| 27 | web site. It has some articles on file systems, the most relevant being
|
|---|
| 28 | the <A
|
|---|
| 29 | HREF="http://kamikazow.fortunecity.de/benewsletter/volume_III/Issue20.html#Insight">One
|
|---|
| 30 | File Network File System</A>, which shows one way of combining a user space
|
|---|
| 31 | program with a kernel file system stub. Another good one is <A
|
|---|
| 32 | HREF="http://www.beatjapan.org/mirror/www.be.com/aboutbe/benewsletter/Issue52.html#Insight">about
|
|---|
| 33 | the FSP</A> (file system protocol). The prior issue describes what <A
|
|---|
| 34 | HREF="http://www.beatjapan.org/mirror/www.be.com/aboutbe/benewsletter/Issue51.html#Insight">features
|
|---|
| 35 | the BFS supports</A>. There are lots of other tangentially related articles,
|
|---|
| 36 | such as ones on device drivers, programming in kernel mode, debugging, etc.
|
|---|
| 37 |
|
|---|
| 38 | <P>There's also the very good <CITE>Practical File System Design</CITE> book
|
|---|
| 39 | by Dominic Giampaolo. Since that book is out of print, it's available as free download from <A HREF="http://www.letterp.com/~dbg/">Dominic's web site</A>.
