- containing an MBR or GPT disk label, also optionally compressed with gzip, bzip2 or xz. In either case,

- operation (as in that case we know the total size on disk). If a socket or pipe is specified, progress information is not
- available. The file descriptor argument is followed by a local name for the image. This should be a

- pre-existing image with the same name is removed before starting the operation. Otherwise, the

- compressed with xz, bzip2 or gzip. The second argument is a local name for the image. It should be
- suitable as a hostname, similarly to the matching argument of the <function>ImportTar()</function> and
- <function>ImportRaw()</function> methods above. The third argument indicates the verification mode for
- the image. It may be one of <literal>no</literal>, <literal>checksum</literal>,
- <literal>signature</literal>. <literal>no</literal> turns off any kind of verification of the image;
- <literal>checksum</literal> looks for a <filename>SHA256SUM</filename> file next to the downloaded

+ or whether to fail (if <literal>false</literal>). In case of
+ <function>PullTarEx()</function>/<function>PullRawEx()</function> the last argument is a 64bit flags

+ of the downloaded image shell be kept, in addition for the local copy of the image. The
+ <function>…_Ex()</function> variants also expect an image class string (as above). Like the import and
+ export calls above, these calls return a pair of transfer identifier and object path for the ongoing
download.</para>
