nvme_mi_admin_identify_partial - Perform an Admin identify command, and retrieve
partial response data.
int nvme_mi_admin_identify_partial (nvme_mi_ctrl_t ctrl ,
struct nvme_identify_args *args , off_t offset ,
size_t size );
- 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
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
The nvme command status if a response was received (see
enum
nvme_status_field) or -1 with errno set otherwise.
