 * </ulink>) will fail unless those disks are accessible via the same
 * device path locally too.
 * 
 * The optional @libvirturi parameter sets the libvirt URI (see <ulink
 * url='http://libvirt.org/uri.html'> http://libvirt.org/uri.html
 * </ulink>). If this is not set then we connect to the default libvirt URI
 * (or one set through an environment variable, see the libvirt
 * documentation for full details).
 * 
 * The optional @live flag controls whether this call will try to connect
 * to a running virtual machine @guestfsd process if it sees a suitable
 * &lt;channel&gt; element in the libvirt XML definition. The default (if
 * the flag is omitted) is never to try. See "ATTACHING TO RUNNING DAEMONS"
 * in guestfs(3) for more information.
 * 
 * If the @allowuuid flag is true (default is false) then a UUID *may* be
 * passed instead of the domain name. The @dom string is treated as a UUID
 * first and looked up, and if that lookup fails then we treat @dom as a
 * name as usual.
 * 
 * The optional @readonlydisk parameter controls what we do for disks which
 * are marked &lt;readonly/&gt; in the libvirt XML. Possible values are:
 * 
 * readonlydisk = "error"
 * If @readonly is false:
 * 
 * The whole call is aborted with an error if any disk with the
 * &lt;readonly/&gt; flag is found.
 * 
 * If @readonly is true:
 * 
 * Disks with the &lt;readonly/&gt; flag are added read-only.
 * 
 * readonlydisk = "read"
 * If @readonly is false:
 * 
 * Disks with the &lt;readonly/&gt; flag are added read-only. Other
 * disks are added read/write.
 * 
 * If @readonly is true:
 * 
 * Disks with the &lt;readonly/&gt; flag are added read-only.
 * 
 * readonlydisk = "write" (default)
 * If @readonly is false:
 * 
 * Disks with the &lt;readonly/&gt; flag are added read/write.
 * 
 * If @readonly is true:
 * 
 * Disks with the &lt;readonly/&gt; flag are added read-only.
 * 
 * readonlydisk = "ignore"
 * If @readonly is true or false:
 * 
 * Disks with the &lt;readonly/&gt; flag are skipped.
 * 
 * The other optional parameters are passed directly through to
 * guestfs_session_add_drive_opts().
 * 
 * Returns: the returned value, or -1 on error

/**
 * guestfs_session_add_drive:
 * @session: (transfer none): A GuestfsSession object
 * @filename: (transfer none) (type utf8):
 * @optargs: (transfer none) (allow-none): a GuestfsAddDrive containing optional arguments
 * @err: A GError object to receive any generated errors
 *
 * add an image to examine or modify
 *
 * This function adds a disk image called filename to the handle. filename
 * may be a regular host file or a host device.
 * 
 * When this function is called before guestfs_session_launch() (the usual
 * case) then the first time you call this function, the disk appears in
 * the API as /dev/sda, the second time as /dev/sdb, and so on.
 * 
 * In libguestfs &ge; 1.20 you can also call this function after launch
 * (with some restrictions). This is called "hotplugging". When
 * hotplugging, you must specify a @label so that the new disk gets a
 * predictable name. For more information see "HOTPLUGGING" in guestfs(3).
 * 
 * You don't necessarily need to be root when using libguestfs. However you
 * obviously do need sufficient permissions to access the filename for
 * whatever operations you want to perform (ie. read access if you just
 * want to read the image or write access if you want to modify the image).
 * 
 * This call checks that filename exists.
 * 
 * filename may be the special string "/dev/null". See "NULL DISKS" in
 * guestfs(3).
 * 
 * The optional arguments are:
 * 
 * @readonly
 * If true then the image is treated as read-only. Writes are still
 * allowed, but they are stored in a temporary snapshot overlay which
 * is discarded at the end. The disk that you add is not modified.
 * 
 * @format
 * This forces the image format. If you omit this (or use
 * guestfs_session_add_drive() or guestfs_session_add_drive_ro()) then
 * the format is automatically detected. Possible formats include @raw
 * and @qcow2.
 * 
 * Automatic detection of the format opens you up to a potential
 * security hole when dealing with untrusted raw-format images. See
 * CVE-2010-3851 and <ulink
 * url='https://bugzilla.redhat.com/show_bug.cgi?id=642934'>
 * RHBZ&num;642934 </ulink>. Specifying the format closes this security
 * hole.
 * 
 * @iface
 * This rarely-used option lets you emulate the behaviour of the
 * deprecated guestfs_session_add_drive_with_if() call (q.v.)
 * 
 * @name
 * The name the drive had in the original guest, e.g. /dev/sdb. This is
 * used as a hint to the guest inspection process if it is available.
 * 
 * @label
 * Give the disk a label. The label should be a unique, short string
 * using *only* ASCII characters "[a-zA-Z]". As well as its usual name
 * in the API (such as /dev/sda), the drive will also be named
 * /dev/disk/guestfs/*label*.
 * 
 * See "DISK LABELS" in guestfs(3).
 * 
 * @protocol
 * The optional protocol argument can be used to select an alternate
 * source protocol.
 * 
 * See also: "REMOTE STORAGE" in guestfs(3).
 * 
 * "protocol = "file""
 * filename is interpreted as a local file or device. This is the
 * default if the optional protocol parameter is omitted.
 * 
 * "protocol = "ftp"|"ftps"|"http"|"https"|"tftp""
 * Connect to a remote FTP, HTTP or TFTP server. The @server
 * parameter must also be supplied - see below.
 * 
 * See also: "FTP, HTTP AND TFTP" in guestfs(3)
 * 
 * "protocol = "gluster""
 * Connect to the GlusterFS server. The @server parameter must also
 * be supplied - see below.
 * 
 * See also: "GLUSTER" in guestfs(3)
 * 
 * "protocol = "iscsi""
 * Connect to the iSCSI server. The @server parameter must also be
 * supplied - see below. The @username parameter may be supplied.
 * See below. The @secret parameter may be supplied. See below.
 * 
 * See also: "ISCSI" in guestfs(3).
 * 
 * "protocol = "nbd""
 * Connect to the Network Block Device server. The @server
 * parameter must also be supplied - see below.
 * 
 * See also: "NETWORK BLOCK DEVICE" in guestfs(3).
 * 
 * "protocol = "rbd""
 * Connect to the Ceph (librbd/RBD) server. The @server parameter
 * must also be supplied - see below. The @username parameter may
 * be supplied. See below. The @secret parameter may be supplied.
 * See below.
 * 
 * See also: "CEPH" in guestfs(3).
 * 
 * "protocol = "sheepdog""
 * Connect to the Sheepdog server. The @server parameter may also
 * be supplied - see below.
 * 
 * See also: "SHEEPDOG" in guestfs(3).
 * 
 * "protocol = "ssh""
 * Connect to the Secure Shell (ssh) server.
 * 
 * The @server parameter must be supplied. The @username parameter
 * may be supplied. See below.
 * 
 * See also: "SSH" in guestfs(3).
 * 
 * @server
 * For protocols which require access to a remote server, this is a
 * list of server(s).
 * 
 * <![CDATA[Protocol       Number of servers required]]>
 * 
 * <![CDATA[--------       --------------------------]]>
 * 
 * <![CDATA[file           List must be empty or param not used at all]]>
 * 
 * <![CDATA[ftp|ftps|http|https|tftp  Exactly one]]>
 * 
 * <![CDATA[gluster        Exactly one]]>
 * 
 * <![CDATA[iscsi          Exactly one]]>
 * 
 * <![CDATA[nbd            Exactly one]]>
 * 
 * <![CDATA[rbd            Zero or more]]>
 * 
 * <![CDATA[sheepdog       Zero or more]]>
 * 
 * <![CDATA[ssh            Exactly one]]>
 * 
 * Each list element is a string specifying a server. The string must
 * be in one of the following formats:
 * 
 * <![CDATA[hostname]]>
 * 
 * <![CDATA[hostname:port]]>
 * 
 * <![CDATA[tcp:hostname]]>
 * 
 * <![CDATA[tcp:hostname:port]]>
 * 
 * <![CDATA[unix:/path/to/socket]]>
 * 
 * If the port number is omitted, then the standard port number for the
 * protocol is used (see /etc/services).
 * 
 * @username
 * For the @ftp, @ftps, @http, @https, @iscsi, @rbd, @ssh and @tftp
 * protocols, this specifies the remote username.
 * 
 * If not given, then the local username is used for @ssh, and no
 * authentication is attempted for ceph. But note this sometimes may
 * give unexpected results, for example if using the libvirt backend
 * and if the libvirt backend is configured to start the qemu appliance
 * as a special user such as "qemu.qemu". If in doubt, specify the
 * remote username you want.
 * 
 * @secret
 * For the @rbd protocol only, this specifies the 'secret' to use when
 * connecting to the remote device. It must be base64 encoded.
 * 
 * If not given, then a secret matching the given username will be
 * looked up in the default keychain locations, or if no username is
 * given, then no authentication will be used.
 * 
 * @cachemode
 * Choose whether or not libguestfs will obey sync operations (safe but
 * slow) or not (unsafe but fast). The possible values for this string
 * are:
 * 
 * "cachemode = "writeback""
 * This is the default.
 * 
 * Write operations in the API do not return until a write(2) call
 * has completed in the host [but note this does not imply that
 * anything gets written to disk].
 * 
 * Sync operations in the API, including implicit syncs caused by
 * filesystem journalling, will not return until an fdatasync(2)
 * call has completed in the host, indicating that data has been
 * committed to disk.
 * 
 * "cachemode = "unsafe""
 * In this mode, there are no guarantees. Libguestfs may cache
 * anything and ignore sync requests. This is suitable only for
 * scratch or temporary disks.
 * 
 * @discard
 * Enable or disable discard (a.k.a. trim or unmap) support on this
 * drive. If enabled, operations such as guestfs_session_fstrim() will
 * be able to discard / make thin / punch holes in the underlying host
 * file or device.
 * 
 * Possible discard settings are:
 * 
 * "discard = "disable""
 * Disable discard support. This is the default.
 * 
 * "discard = "enable""
 * Enable discard support. Fail if discard is not possible.
 * 
 * "discard = "besteffort""
 * Enable discard support if possible, but don't fail if it is not
 * supported.
 * 
 * Since not all backends and not all underlying systems support
 * discard, this is a good choice if you want to use discard if
 * possible, but don't mind if it doesn't work.
 * 
 * @copyonread
 * The boolean parameter @copyonread enables copy-on-read support. This
 * only affects disk formats which have backing files, and causes reads
 * to be stored in the overlay layer, speeding up multiple reads of the
 * same area of disk.
 * 
 * The default is false.
 * 
 * Returns: true on success, false on error
 * Since: 0.3

 * @err: A GError object to receive any generated errors
 *
 * add the disk(s) from a libvirt domain
 *
 * This function adds the disk(s) attached to the libvirt domain @dom. It
 * works by requesting the domain XML from libvirt, parsing it for disks,
 * and calling guestfs_session_add_drive_opts() on each one.
 * 
 * In the C API we declare "void *dom", but really it has type
 * "virDomainPtr dom". This is so we don't need &lt;libvirt.h&gt;.
 * 
 * The number of disks added is returned. This operation is atomic: if an
 * error is returned, then no disks are added.
 * 
 * This function does some minimal checks to make sure the libvirt domain
 * is not running (unless @readonly is true). In a future version we will
 * try to acquire the libvirt lock on each disk.
 * 
 * Disks must be accessible locally. This often means that adding disks
 * from a remote libvirt connection (see <ulink
 * url='http://libvirt.org/remote.html'> http://libvirt.org/remote.html
 * </ulink>) will fail unless those disks are accessible via the same
 * device path locally too.
 * 
 * The optional @live flag controls whether this call will try to connect
 * to a running virtual machine @guestfsd process if it sees a suitable
 * &lt;channel&gt; element in the libvirt XML definition. The default (if
 * the flag is omitted) is never to try. See "ATTACHING TO RUNNING DAEMONS"
 * in guestfs(3) for more information.
 * 
 * The optional @readonlydisk parameter controls what we do for disks which
 * are marked &lt;readonly/&gt; in the libvirt XML. See
 * guestfs_session_add_domain() for possible values.
 * 
 * The other optional parameters are passed directly through to
 * guestfs_session_add_drive_opts().
 * 
 * Returns: the returned value, or -1 on error

 *
 * test availability of some parts of the API
 *
 * This command is used to check the availability of some groups of
 * functionality in the appliance, which not all builds of the libguestfs
 * appliance will be able to provide.
 * 
 * The libguestfs groups, and the functions that those groups correspond
 * to, are listed in "AVAILABILITY" in guestfs(3). You can also fetch this
 * list at runtime by calling guestfs_session_available_all_groups().
 * 
 * The argument @groups is a list of group names, eg: "["inotify",
 * "augeas"]" would check for the availability of the Linux inotify
 * functions and Augeas (configuration file editing) functions.
 * 
 * The command returns no error if *all* requested groups are available.
 * 
 * It fails with an error if one or more of the requested groups is
 * unavailable in the appliance.
 * 
 * If an unknown group name is included in the list of groups then an error
 * is always returned.
 * 
 * *Notes:*
 * 
 * *   guestfs_session_feature_available() is the same as this call, but
 * with a slightly simpler to use API: that call returns a boolean
 * true/false instead of throwing an error.
 * 
 * *   You must call guestfs_session_launch() before calling this function.
 * 
 * The reason is because we don't know what groups are supported by the
 * appliance/daemon until it is running and can be queried.
 * 
 * *   If a group of functions is available, this does not necessarily mean
 * that they will work. You still have to check for errors when calling
 * individual API functions even if they are available.
 * 
 * *   It is usually the job of distro packagers to build complete
 * functionality into the libguestfs appliance. Upstream libguestfs, if
 * built from source with all requirements satisfied, will support
 * everything.
 * 
 * *   This call was added in version 1.0.80. In previous versions of
 * libguestfs all you could do would be to speculatively execute a
 * command to find out if the daemon implemented it. See also
 * guestfs_session_version().
 * 
 * See also guestfs_session_filesystem_available().

 *
 * This can be used to resolve case insensitive paths on a filesystem which

 * from Windows configuration files or the Windows Registry, to the true
 * path.
 * 
 * The command handles a peculiarity of the Linux ntfs-3g filesystem driver
 * (and probably others), which is that although the underlying filesystem
 * is case-insensitive, the driver exports the filesystem to Linux as
 * case-sensitive.
 * 
 * One consequence of this is that special directories such as C:\windows
 * may appear as /WINDOWS or /windows (or other things) depending on the
 * precise details of how they were created. In Windows itself this would
 * not be a problem.
 * 
 * Bug or feature? You decide: <ulink

 * of each element in the path. It will return a resolved path if either
 * the full path or its parent directory exists. If the parent directory
 * exists but the full path does not, the case of the parent directory will
 * be correctly resolved, and the remainder appended unmodified. For
 * example, if the file "/Windows/System32/netkvm.sys" exists:
 * 
 * guestfs_session_case_sensitive_path() ("/windows/system32/netkvm.sys")
 * "Windows/System32/netkvm.sys"

 *
 * The four calls guestfs_session_copy_device_to_device(),
 * guestfs_session_copy_device_to_file(),
 * guestfs_session_copy_file_to_device(), and
 * guestfs_session_copy_file_to_file() let you copy from a source
 * (device|file) to a destination (device|file).
 * 
 * Partial copies can be made since you can specify optionally the source
 * offset, destination offset and size to copy. These values are all
 * specified in bytes. If not given, the offsets both default to zero, and
 * the size defaults to copying as much as possible until we hit the end of
 * the source.
 * 
 * The source and destination may be the same object. However overlapping
 * regions may not be copied correctly.
 * 
 * If the destination is a file, it is created if required. If the
 * destination file is not large enough, it is extended.
 * 
 * If the destination is a file and the @append flag is not set, then the
 * destination file is truncated. If the @append flag is set, then the copy
 * appends to the destination file. The @append flag currently cannot be
 * set for devices.
 * 
 * If the @sparse flag is true then the call avoids writing blocks that
 * contain only zeroes, which can help in some situations where the backing
 * disk is thin-provisioned. Note that unless the target is already zeroed,
 * using this option will result in incorrect copying.

 *
 * This returns the file attributes associated with file.

 * file attributes are set for this file.
 * 
 * These attributes are only present when the file is located on an
 * ext2/3/4 filesystem. Using this call on other filesystem types will
 * result in an error.
 * 
 * The characters (file attributes) in the returned string are currently:
 * 
 * 'A' When the file is accessed, its atime is not modified.
 * 
 * 'a' The file is append-only.
 * 
 * 'c' The file is compressed on-disk.
 * 
 * 'D' (Directories only.) Changes to this directory are written
 * synchronously to disk.
 * 
 * 'd' The file is not a candidate for backup (see dump(8)).
 * 
 * 'E' The file has compression errors.
 * 
 * 'e' The file is using extents.
 * 
 * 'h' The file is storing its blocks in units of the filesystem blocksize
 * instead of sectors.
 * 
 * 'I' (Directories only.) The directory is using hashed trees.
 * 
 * 'i' The file is immutable. It cannot be modified, deleted or renamed. No
 * link can be created to this file.
 * 
 * 'j' The file is data-journaled.
 * 
 * 's' When the file is deleted, all its blocks will be zeroed.
 * 
 * 'S' Changes to this file are written synchronously to disk.
 * 
 * 'T' (Directories only.) This is a hint to the block allocator that
 * subdirectories contained in this directory should be spread across
 * blocks. If not present, the block allocator will try to group
 * subdirectories together.
 * 
 * 't' For a file, this disables tail-merging. (Not used by upstream
 * implementations of ext2.)
 * 
 * 'u' When the file is deleted, its blocks will be saved, allowing the
 * file to be undeleted.
 * 
 * 'X' The raw contents of the compressed file may be accessed.
 * 
 * 'Z' The compressed file is dirty.
 * 
 * More file attributes may be added to this list later. Not all file
 * attributes may be set for all kinds of files. For detailed information,

 * Note that keys are drive letters. For Windows, the key is case
 * insensitive and just contains the drive letter, without the customary
 * colon separator character.
 * 
 * In future we may support other operating systems that also used drive
 * letters, but the keys for those might not be case insensitive and might

 *
 * This function returns an icon corresponding to the inspected operating

 * (re-encoded to PNG if necessary).
 * 
 * If it was not possible to get an icon this function returns a
 * zero-length (non-NULL) buffer. *Callers must check for this case*.
 * 
 * Libguestfs will start by looking for a file called /etc/favicon.png or
 * C:\etc\favicon.png and if it has the correct format, the contents of
 * this file will be returned. You can disable favicons by passing the
 * optional @favicon boolean as false (default is true).
 * 
 * If finding the favicon fails, then we look in other places in the guest
 * for a suitable icon.
 * 
 * If the optional @highquality boolean is true then only high quality
 * icons are returned, which means only icons of high resolution with an
 * alpha channel. The default (false) is to return any icon we can, even if
 * it is of substandard quality.
 * 
 * Notes:
 * 
 * *   Unlike most other inspection API calls, the guest's disks must be
 * mounted up before you call this, since it needs to read information
 * from the guest filesystem during the call.
 * 
 * *   Security: The icon data comes from the untrusted guest, and should
 * be treated with caution. PNG files have been known to contain
 * exploits. Ensure that libpng (or other relevant libraries) are fully
 * up to date before trying to process or display the icon.
 * 
 * *   The PNG image returned can be any size. It might not be square.
 * Libguestfs tries to return the largest, highest quality icon
 * available. The application must scale the icon to the required size.
 * 
 * *   Extracting icons from Windows guests requires the external @wrestool
 * program from the @icoutils package, and several programs (@bmptopnm,
 * @pnmtopng, @pamcut) from the @netpbm package. These must be
 * installed separately.
 * 
 * *   Operating system icons are usually trademarks. Seek legal advice
 * before using trademarks in applications.

 *
 * This function uses other libguestfs functions and certain heuristics to
 * inspect the disk(s) (usually disks belonging to a virtual machine),
 * looking for operating systems.
 * 
 * The list returned is empty if no operating systems were found.
 * 
 * If one operating system was found, then this returns a list with a
 * single element, which is the name of the root filesystem of this
 * operating system. It is also possible for this function to return a list
 * containing more than one element, indicating a dual-boot or multi-boot
 * virtual machine, with each element being the root filesystem of one of
 * the operating systems.
 * 
 * You can pass the root string(s) returned to other
 * "guestfs_inspect_get_*" functions in order to query further information
 * about each operating system, such as the name and version.
 * 
 * This function uses other libguestfs features such as
 * guestfs_session_mount_ro() and guestfs_session_umount_all() in order to
 * mount and unmount filesystems and look at the contents. This should be
 * called with no disks currently mounted. The function may also use
 * Augeas, so any existing Augeas handle will be closed.
 * 
 * This function cannot decrypt encrypted disks. The caller must do that
 * first (supplying the necessary keys) if the disk is encrypted.
 * 
 * Please read "INSPECTION" in guestfs(3) for more details.
 * 
 * See also guestfs_session_list_filesystems().
 *

 * @session: (transfer none): A GuestfsSession object
 * @exemptpath: (transfer none) (type utf8):
 * @err: A GError object to receive any generated errors
 *
 * create a mountpoint
 *
 * guestfs_session_mkmountpoint() and guestfs_session_rmmountpoint() are
 * specialized calls that can be used to create extra mountpoints before
 * mounting the first filesystem.
 * 
 * These calls are *only* necessary in some very limited circumstances,
 * mainly the case where you want to mount a mix of unrelated and/or
 * read-only filesystems together.
 * 
 * For example, live CDs often contain a "Russian doll" nest of
 * filesystems, an ISO outer layer, with a squashfs image inside, with an
 * ext2/3 image inside that. You can unpack this as follows in guestfish:
 * 
 * <![CDATA[add-ro Fedora-11-i686-Live.iso]]>
 * 
 * <![CDATA[run]]>
 * 
 * <![CDATA[mkmountpoint /cd]]>
 * 
 * <![CDATA[mkmountpoint /sqsh]]>
 * 
 * <![CDATA[mkmountpoint /ext3fs]]>
 * 
 * <![CDATA[mount /dev/sda /cd]]>
 * 
 * <![CDATA[mount-loop /cd/LiveOS/squashfs.img /sqsh]]>
 * 
 * <![CDATA[mount-loop /sqsh/LiveOS/ext3fs.img /ext3fs]]>
 * 
 * The inner filesystem is now unpacked under the /ext3fs mountpoint.
 * 
 * guestfs_session_mkmountpoint() is not compatible with
 * guestfs_session_umount_all(). You may get unexpected errors if you try
 * to mix these calls. It is safest to manually unmount filesystems and
 * remove mountpoints after use.
 * 
 * guestfs_session_umount_all() unmounts filesystems by sorting the paths
 * longest first, so for this to work for manual mountpoints, you must
 * ensure that the innermost mountpoints have the longest pathnames, as in
 * the example code above.
 * 
 * For more details see <ulink
 * url='https://bugzilla.redhat.com/show_bug.cgi?id=599503'>
 * http://bugzilla.redhat.com/show_bug.cgi?id=599503 </ulink>
 *

 * @force
 * Force tune2fs to complete the operation even in the face of errors.
 * This is the same as the tune2fs @-f option.
 *

 * Set the number of mounts after which the filesystem is checked by
 * e2fsck(8). If this is @0 then the number of mounts is disregarded.
 * This is the same as the tune2fs @-c option.
 * 
 * @mountcount
 * Set the number of times the filesystem has been mounted. This is the
 * same as the tune2fs @-C option.
 * 
 * @errorbehavior
 * Change the behavior of the kernel code when errors are detected.
 * Possible values currently are: @continue, @remount-ro, @panic. In
 * practice these options don't really make any difference,
 * particularly for write errors.
 * 
 * This is the same as the tune2fs @-e option.
 * 
 * @group
 * Set the group which can use reserved filesystem blocks. This is the
 * same as the tune2fs @-g option except that it can only be specified
 * as a number.
 * 
 * @intervalbetweenchecks
 * Adjust the maximal time between two filesystem checks (in seconds).
 * If the option is passed as @0 then time-dependent checking is
 * disabled.
 * 
 * This is the same as the tune2fs @-i option.
 * 
 * @reservedblockspercentage
 * Set the percentage of the filesystem which may only be allocated by
 * privileged processes. This is the same as the tune2fs @-m option.
 * 
 * @lastmounteddirectory
 * Set the last mounted directory. This is the same as the tune2fs @-M
 * option.
 * 
 * @reservedblockscount Set the number of reserved filesystem blocks. This
 * is the same as the tune2fs @-r option.
 * @user
 * Set the user who can use the reserved filesystem blocks. This is the
 * same as the tune2fs @-u option except that it can only be specified
 * as a number.
 * 
 * To get the current values of filesystem parameters, see
 * guestfs_session_tune2fs_l(). For precise details of how tune2fs works,

 * caller's responsibility to clean up if necessary.
 * 
 * There are two common places that you might call
 * guestfs_session_user_cancel():
 * 
 * In an interactive text-based program, you might call it from a @SIGINT
 * signal handler so that pressing "^C" cancels the current operation. (You
