just want to read the image or write access if you want to modify the
image).
-This is equivalent to the qemu parameter C<-drive file=filename,cache=off>.
+This is equivalent to the qemu parameter
+C<-drive file=filename,cache=off,if=virtio>.
Note that this call checks for the existence of C<filename>. This
stops you from specifying other types of drive which are supported
changes to be committed, although qemu can support this.

+=head2 mkfifo
+
+ mkfifo mode path
+
+This call creates a FIFO (named pipe) called C<path> with
+mode C<mode>. It is just a convenient wrapper around
+C<mknod>.
+
=head2 mkfs
mkfs fstype device
or LVM logical volume). The filesystem type is C<fstype>, for
example C<ext3>.
+=head2 mknod
+
+ mknod mode devmajor devminor path
+
+This call creates block or character special devices, or
+named pipes (FIFOs).
+
+The C<mode> parameter should be the mode, using the standard
+constants. C<devmajor> and C<devminor> are the
+device major and minor numbers, only used when creating block
+and character special devices.
+
+=head2 mknod-b
+
+ mknod-b mode devmajor devminor path
+
+This call creates a block device node called C<path> with
+mode C<mode> and device major/minor C<devmajor> and C<devminor>.
+It is just a convenient wrapper around C<mknod>.
+
+=head2 mknod-c
+
+ mknod-c mode devmajor devminor path
+
+This call creates a char device node called C<path> with
+mode C<mode> and device major/minor C<devmajor> and C<devminor>.
+It is just a convenient wrapper around C<mknod>.
+
=head2 mkswap
mkswap device
as end of line). For those you need to use the C<read-file>
function which has a more complex interface.
+=head2 readdir
+
+ readdir dir
+
+This returns the list of directory entries in directory C<dir>.
+
+All entries in the directory are returned, including C<.> and
+C<..>. The entries are I<not> sorted, but returned in the same
+order as the underlying filesystem.
+
+This function is primarily intended for use by programs. To
+get a simple list of names, use C<ls>. To get a printable
+directory for human consumption, use C<ll>.

=head2 resize2fs
resize2fs device
clearly defined, and depends on both the version of C<tune2fs>
that libguestfs was built against, and the filesystem itself.
+=head2 umask
+
+ umask mask
+
+This function sets the mask used for creating new files and
+device nodes to C<mask & 0777>.
+
+Typical umask values would be C<022> which creates new files
+with permissions like "-rw-r--r--" or "-rwxr-xr-x", and
+C<002> which creates new files with permissions like
+"-rw-rw-r--" or "-rwxrwxr-x".
+
+The default umask is C<022>. This is important because it
+means that directories and device nodes will be created with
+C<0644> or C<0755> mode even if you specify C<0777>.
+
+See also L<umask(2)>, C<mknod>, C<mkdir>.
+
+This call returns the previous umask.
