Thanks a lot. I was trying to copy on local disk and guestfs_download () solved my problem. Now I am trying to modify source code of guestfs_download () to extract file in memory. Can you guide me what should i do to achieve that. Mohsin On Fri, Feb 10, 2017 at 2:13 AM, Richard W.M. Jones <rjones@redhat.com> wrote: > On Thu, Feb 09, 2017 at 03:24:53PM +0...

Hi, I have tried to extract *.vhd* file using guestfs library. I am able to list all files inside my archive using *guestfs_ls* also * guestfs_list_filesystems()* retruns right File system information. I am trying to extract files from inside archive using *guestfs_copy_device_to_file() * but it returns following error (error: copy_device_to_file: unknown option 689330304 (this can happen if a

Download the file to the local host? If so use guestfs_download: guestfs_download (g, "/file-to-extract.exe", "local-file.exe"); BTW you should check for errors from C API calls. http://libguestfs.org/guestfs.3.html#downloading http://libguestfs.org/guestfs.3.html#error-handling Rich. -- Richard Jones, Virtualization Group, Red H...

In APIs such as guestfs_download, when the FileOut parameter exactly matches "/dev/stdout" or "/dev/stderr", don't reopen the possibly redirected output file with O_TRUNC (truncate). Instead dup the file descriptor. This magic behaviour doesn't happen for /dev/fd/* (or any other output file) allowing...

This two-part patch implements the 'hexedit' command described here: http://rwmj.wordpress.com/2010/09/18/new-feature-guestfish-hexedit/#content The first part implements two new APIs for partial writing and reading of files. These are modelled after guestfs_upload and guestfs_download but allow you to specify an offset and (for download only) a size: int guestfs_download_offset (guestfs_h *g, const char *remotefilename, const char *filename, int64_t offset, int64_t size); int guestfs_upload_offset (guestfs_h *g, const char *filename, const char *remotefilename, int64_t...

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

Hi Nikolay, We use guestfish, so I preferred to use commands supported by guestfish. I tried as below but "realpath" is not working after I have the target path from symlink. --> Check if the path has a symlink. is-symlink path Ex. - is-symlink "/etc/resolv.conf" -> return true --> If it's true then get target link path readlink path ex. - readlink
