How to develop a FS driver

mjs · Post by **mjs** » Mon Feb 21, 2005 6:09 pm

Hi,

how can I find information about developing a file system driver? I looked into fs/template/template.c but it doesn't seem to fit my needs.

The driver I wanted to implement is something like a RAM disk but it doesn't use a "real" FS. I thought about something like the dynamic-size RAM disk from AMIGA OS that doesn't need a storage device. This FS doesn't need to be mounted with a storage device.

Don't know if I could make it clear what I want ...

It would be nice if s/o can tell me:
- which functions are needed
- where are the structures defined
- which command codes are valid
- what are the valid return codes
- what are the pre-/post-conditions the implemented functions must meet

I cannot find anything in the MSDN Library Jan 2005, PSDK, DDK NT4.0, DDK W2K, DDK WIN98.

Regards,
Mark

Yesterday I've just seen a example for something like that. I'll look if I can find it again.

Here it is:

God bless the browser's history.

Hi,

I know I can buy the NT IFS kit but I really don't like the idea of buying it for 900 USD ...

EDIT: Do you know any other sources where I can find specs about IFS development?

Regards,
Mark

Thank you for showing me this ... but ... I saw this too but where can I find specifications about it - and not only implementations?

For NT/2000/XP/2003 you definitely need to buy the IFS kit from MS.

If your goal is contributing a port of a file system driver, from Linux to ROS, look example code here:

Could someone merge those filesystems into the main tree.

The swapfs moded would make reactos the first windows to be able to use and share linux swap partions.
