+
+ int guestfs_sfdisk (guestfs_h *handle,
+ const char *device,
+ int cyls,
+ int heads,
+ int sectors,
+ char * const* const lines);
+
+This is a direct interface to the L<sfdisk(8)> program for creating
+partitions on block devices.
+
+C<device> should be a block device, for example C</dev/sda>.
+
+C<cyls>, C<heads> and C<sectors> are the number of cylinders, heads
+and sectors on the device, which are passed directly to sfdisk as
+the I<-C>, I<-H> and I<-S> parameters. If you pass C<0> for any
+of these, then the corresponding parameter is omitted. Usually for
+'large' disks, you can just pass C<0> for these, but for small
+(floppy-sized) disks, sfdisk (or rather, the kernel) cannot work
+out the right geometry and you will need to tell it.
+
+C<lines> is a list of lines that we feed to C<sfdisk>. For more
+information refer to the L<sfdisk(8)> manpage.
+
+To create a single partition occupying the whole disk, you would
+pass C<lines> as a single element list, when the single element being
+the string C<,> (comma).
+
+This function returns 0 on success or -1 on error.

+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.
