Detailed Description

The universal unpacker code to unpack a disk file system.

Definition in file ununpack-disk.c.

Function Documentation

int ExtractDisk	(	char *	Source,
		char *	FStype,
		char *	Destination
	)

Given a disk image, type of system, and a directory, extract all files!

This can handle any filesystem supported by fls/icat.

Special: FAT is case-insensitive, so everything is converted to lowercase.

Uses the following external commands: fls icat

icat and fls are from the package "sleuthkit".

Note

This spawns multiple processes.

Parameters

Source
FStype	filesystem type
Destination

Returns

0 on success, non-zero on failure.

		char *	Source
	)

Given a disk, load in all of the file permissions. Assumes Source is already quote-tainted!

Source	Source filepath

Returns

permlist

Note

Strings MUST be null terminated!

Valid characters: 0-9 and hyphen.

Parameters

Inode1
Inode2

Returns

1 on match, 0 on miss.
