DESCRIPTION
-----------
The zone append command writes the logical blocks specified by the command to
the medium from the data data buffer provided. Will use stdin by default
if you don't provide a file.

On success, the program will report the LBA that was assigned to the data for
the append operation.

OPTIONS
-------
-n <NUM>::
--namespace-id=<NUM>::
	Use the provided namespace id for the command. If not provided, the
	namespace id of the block device will be used. If the command is issued
	to a non-block device, the parameter is required.

-s <IONUM>::
--zslba=<IONUM>::

-z <IONUM>::
--data-size=<IONUM>::
	Size of data, in bytes.

-y <IONUM>::
--metadata-size=<IONUM>::
	Size of metadata in bytes.

-d <FILE>::
--data=<FILE>::
	Data file providing the data to write. If none provided, contents are
	sent from STDIN.

-M <FILE>::
--metadata=<FILE>::
	Metadata file, if necessary.

-l::
--limited-retry::
	Sets the limited retry flag.

-f::
--force-unit-access::
	Set the force-unit access flag.

-r <NUM>::
--ref-tag=<NUM>::
	Optional reftag when used with protection information.

-m <NUM>::
--app-tag-mask=<NUM>::
	Optional application tag mask when used with protection information.

-a <NUM>::
--app-tag=<NUM>::
	Optional application tag when used with protection information.

-p <NUM>::
--prinfo=<NUM>::
	Protection Information field definition.

EXAMPLES
--------
* Append the data "hello world" into 4k worth of blocks into the zone starting
  at block 0 for namespace 1:
+
