+ const char *tarfile,
+ const char *directory);
+
+This command uploads and unpacks local file C<tarfile> (an
+I<uncompressed> tar file) into C<directory>.

+
+This function returns 0 on success or -1 on error.

+=head2 guestfs_tar_out
+
+ int guestfs_tar_out (guestfs_h *handle,

+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_tgz_in
+
+ int guestfs_tgz_in (guestfs_h *handle,
+ const char *tarball,
+ const char *directory);
+
+This command uploads and unpacks local file C<tarball> (a
+I<gzip compressed> tar file) into C<directory>.
+
+To upload an uncompressed tarball, use C<guestfs_tar_in>.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_tgz_out
+
+ int guestfs_tgz_out (guestfs_h *handle,

=head2 guestfs_touch
int guestfs_touch (guestfs_h *handle,
This function returns 0 on success or -1 on error.
+=head2 guestfs_tune2fs_l
+
+ char **guestfs_tune2fs_l (guestfs_h *handle,
+ const char *device);
+
+This returns the contents of the ext2, ext3 or ext4 filesystem
+superblock on C<device>.
+
+It is the same as running C<tune2fs -l device>. See L<tune2fs(8)>
+manpage for more details. The list of fields returned isn't
+clearly defined, and depends on both the version of C<tune2fs>
+that libguestfs was built against, and the filesystem itself.
+
+This function returns a NULL-terminated array of
+strings, or NULL if there was an error.
+The array of strings will always have length C<2n+1>, where
+C<n> keys and values alternate, followed by the trailing NULL entry.
+I<The caller must free the strings and the array after use>.
+
+=head2 guestfs_umount
+
+ int guestfs_umount (guestfs_h *handle,
+ const char *pathordevice);
+
+This unmounts the given filesystem. The filesystem may be
+specified either by its mountpoint (path) or the device which
+contains the filesystem.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_umount_all
+
+ int guestfs_umount_all (guestfs_h *handle);
+
+This unmounts all mounted filesystems.
+
+Some internal mounts are not unmounted by this call.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_upload
+
+ int guestfs_upload (guestfs_h *handle,
+ const char *filename,
+ const char *remotefilename);
+
+Upload local file C<filename> to C<remotefilename> on the
+filesystem.
+
+C<filename> can also be a named pipe.
+
+See also C<guestfs_download>.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_vgcreate
+
+ int guestfs_vgcreate (guestfs_h *handle,
+ const char *volgroup,
+ char * const* const physvols);
+
+This creates an LVM volume group called C<volgroup>
+from the non-empty list of physical volumes C<physvols>.
+
+This function returns 0 on success or -1 on error.
+
+=head2 guestfs_vgremove
+
+ int guestfs_vgremove (guestfs_h *handle,
+ const char *vgname);
+
+Remove an LVM volume group C<vgname>, (for example C<VG>).
+
+This also forcibly removes all logical volumes in the volume
+group (if any).
+
+This function returns 0 on success or -1 on error.
+
=head2 guestfs_vgs
char **guestfs_vgs (guestfs_h *handle);
List all the volumes groups detected. This is the equivalent
of the L<vgs(8)> command. The "full" version includes all fields.
-This function returns a C<struct guestfs_lvm_vg_list *>.
+This function returns a C<struct guestfs_lvm_vg_list *>
+(see E<lt>guestfs-structs.hE<gt>),
+or NULL if there was an error.
I<The caller must call C<guestfs_free_lvm_vg_list> after use>.
=head2 guestfs_wait_ready
This function returns 0 on success or -1 on error.
+=head2 guestfs_write_file
+
+ int guestfs_write_file (guestfs_h *handle,
+ const char *path,
+ const char *content,
+ int size);
+
+This call creates a file called C<path>. The contents of the
+file is the string C<content> (which can contain any 8 bit data),
+with length C<size>.
+
+As a special case, if C<size> is C<0>
+then the length is calculated using C<strlen> (so in this case
+the content cannot contain embedded ASCII NULs).
+
+This function returns 0 on success or -1 on error.
+
+Because of the message protocol, there is a transfer limit
+of somewhere between 2MB and 4MB. To transfer large files you should use
+FTP.
