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.
