[Libguestfs] [PATCH] ffind API to retrieve a file name given its inode

[Matteo Cafasso]

The ffind API allows to retrieve a file name from a device given its inode.

The function returns a struct "tsknode" which contains the file name, its inode and it's allocation status. The struct will be employed by other APIs as well (fls, ifind etc..).

$ ./run guestfish --ro -a /home/noxdafox/disks/ubuntu.qcow2

><fs> run
><fs> ffind /dev/sda1 2
tsk_name: /
tsk_inode: 2
tsk_allocated: 1

><fs> ffind /dev/sda1 3
tsk_name: /usr/bin/
tsk_inode: 3
tsk_allocated: 0

/usr/bin/ has been reallocated to node 786577

><fs> mount /dev/sda1 /
><fs> stat /usr/bin/
dev: 2049
ino: 786577
...
