iso file structure
 

hi,
i'm trying to do a project to write a device driver for linux to implement a virtual cd device...this device driver will return the appropriate file from an iso image file present in the hard disk...an association wil be made b/n the iso file and the driver....
cd supported applications then wil not require a physical cd device to be present...

For this i need to retrieve files present in the image file.......
so i need to know abt iso file structure..........pls help me by suggesting measures or suggesting tutorials that wil give me a great deal of info abt iso file and file extraction from it......

Have a start at

If I'm not completely mistaken, you not only posted this thread into two forums, but did it again (I'm fairly sure I read about this already some time ago, right?) Didn't you get answers last time, or why are you double-posting this a new time?
EDIT: seems like you only have two posts made, so I may be wrong (I'm sorry if that's the case). However a very similar thread was posted earlier, I'm sure of that. Very similar.

Last time somebody already suggested to take a look at mount and especially it's loop option, which lets mount iso images, which seems to be a great part of your project:
