NAME

       nvme_identify_ns - Retrieves nvme identify namespace

SYNOPSIS

       int nvme_identify_ns (int fd , __u32 nsid , struct nvme_id_ns *ns );

ARGUMENTS

       fd          File descriptor of nvme device

       nsid        Namespace to identify

       ns          User space destination address to transfer the data

DESCRIPTION

       If  the  Namespace  Identifier  (NSID)  field  specifies an active NSID, then the Identify
       Namespace data structure is returned to the host for that specified namespace.

       If the controller supports the Namespace Management capability and the NSID field  is  set
       to  NVME_NSID_ALL,  then  the controller returns an Identify Namespace data structure that
       specifies capabilities that are common across namespaces for this controller.

       See struct nvme_id_ns for details on the structure returned.

RETURN

       The nvme command status if a response was received (see enum nvme_status_field) or -1 with
       errno set otherwise.
