[sleuthkit-users] Writing files to disk

[<sle...@fa...>]

Hi community,
I am working on a small extraction utility using tsk. What I want to to is to find certain files and write them to disk. One could say copy a file from the image I am processing. But all I manage is writing binary data. I want it to work with text files primarily, but in the end with every file type. Just a simple copy so I can open the exported files the same way I would if the image was mounted. I use tsk_fs_file_walk with a callback that does nothing more than an fwrite. But as I said, this way I only write binary data. So what am I doing wrong?
Kind regards
