.SH "DESCRIPTION"
Perform an Identify command, using the Identify command parameters in \fIargs\fP.
The \fIoffset\fP and \fIsize\fP arguments allow the caller to retrieve part of
the identify response. See NVMe-MI section 6.2 for the semantics (and some
handy diagrams) of the offset & size parameters.

Will return an error if the length of the response data (from the controller)
did not match \fIsize\fP.

Unless you're performing a vendor-unique identify command, You'll probably
want to use one of the identify helpers (nvme_mi_admin_identify,
nvme_mi_admin_identify_cns_nsid, or nvme_mi_admin_identify_<type>) instead
of this. If the type of your identify command is standardized but not
yet supported by libnvme-mi, please contact the maintainers.

See: \fIstruct nvme_identify_args\fP
.SH "RETURN"
The nvme command status if a response was received (see
\fIenum nvme_status_field\fP) or -1 with errno set otherwise.
