Hi,

I have a wireless rounter that has a program to control the DNS, users, security etc. It has a USB interface to let user plug in external hard disk.

The embedded system was written by C language on linux OS. Now, I want to develop a module to access the external hard disk. To perform the file system functions:

1. to let user view directories and files,
2. set access right,
3. file share of the directories in the hard disk.

May I ask where can I learn the file system and does any open source or sample code for it?

Thanks for help

You should probably confer with the manufacture of the router. I've never known a router as such. And the closest I've ever been to altering any internals on my router was when I did something out of curiousity. Most of the time the source is closed and they only want you to have limited information in regard to their product. Unless of course you have an open source router...........lol.

Yes, I have part of the C source code of the router.

To perform the file system functions:

1. to let user view directories and files,

And, anyone knows whether cprogramming.com was closed or not?
