NAME

       nvme_mi_admin_identify_partial - Perform an Admin identify command, and retrieve partial response data.

SYNOPSIS

       int  nvme_mi_admin_identify_partial (nvme_mi_ctrl_t ctrl , struct nvme_identify_args *args , off_t offset
       , size_t size );

ARGUMENTS

       ctrl        Controller to process identify command

       args        Identify command arguments

       offset      offset of identify data to retrieve from response

       size        size of identify data to return

DESCRIPTION

       Perform an Identify command, using the  Identify  command  parameters  in  args.   The  offset  and  size
       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 size.

       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: struct nvme_identify_args

RETURN

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