FileSystem

VFS using Fuse

To execute

$make
$./initialise

What is FUSE?

->VFS and FUSE are related, but not quite the same thing. The main purpose of FUSE is to turn things-that-are-almost-like-files-but-not-quite (such as files on a remote server, or inside a ZIP file) into "real" directories and files. See the roster of FUSE filesystems to get an idea of what this is good for; this hopefully will make it clearer why FUSE beats "plain old files" in a lot of circumstances.
->It provides a way to intercept file system calls issued by Linux programs and to redirect
the program flow into a handler (daemon running as a user-level process) function.
->It also helps to mount the file system.
->FUSE helps you in writing a virtual file system.

Workflow

main.c 
    functions start with fs_ 
    Intergrated with fuse (set fuse operations)
    Call syscall functions
syscall.c
    functions start with syscall_ 
    Do all Inode operations
    Call disk functions
disk.c
    functions start with disk_
    Do disk reads and writes

Files

disk.h -Disk emulator
disk.c -Disk emulator
syscall.c - System Calls
syscall.h - System Calls
initialise.c -Initialise disk and inodes
initialise.h -Initialise disk and inodes
log.txt - Log file
write_to_log.h - Writing to a log file
write_to_log.c - Writing to a log file
