<div class="sectionbody">
<div class="paragraph"><p>For the NVMe device given, sends an I/O Command Set Independent
identify namespace command and provides the result and returned structure.</p></div>
<div class="paragraph"><p>The <device> parameter is mandatory and may be either the NVMe character
device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
If the character device is given, the <code>'--namespace-id'</code> option is
mandatory, otherwise it will use the ns-id of the namespace for the block
device you opened. For block devices, the ns-id used can be overridden
with the same option.</p></div>
<div class="paragraph"><p>On success, the structure may be returned in one of several ways depending
on the option flags; the structure may be parsed by the program or the
raw buffer may be printed to stdout.</p></div>
