Expand description

Partition describes a region of one or more block devices, labelled with distinguishing identifiers.

Variants§

§

GetInfo

Get information about the underlying block device.

§

GetStats

Fields

§clear: bool

Returns stats about block device operations. Setting clear will reset stats counters.

§

OpenSession

Fields

§session: ServerEnd<SessionMarker>
§control_handle: PartitionControlHandle

Opens a new FIFO-based session on the block device.

§

ReadBlocks

Fields

§vmo: Vmo
§length: u64
§dev_offset: u64
§vmo_offset: u64

Reads from a block device.

This read does not require exclusive access. length, dev_offset and vmo_offset are specified in bytes, but they must be block-aligned. This method is provided for backward compatibility, and is not intended for new code. New code should use the FIFO interface along with the client libraries to read and write from block devices.

§

WriteBlocks

Fields

§vmo: Vmo
§length: u64
§dev_offset: u64
§vmo_offset: u64

Writes to a block device.

This write does not require exclusive access. length, dev_offset and vmo_offset are specified in bytes, but they must be block-aligned. This method is provided for backward compatibility, and is not intended for new code. New code should use the FIFO interface along with the client libraries to read and write from block devices.

§

GetTypeGuid

Gets the type GUID of the partition (if one exists). If the partition has no type GUID, ZX_ERR_NOT_SUPPORTED is returned.

§

GetInstanceGuid

Gets the instance GUID of the partition (if one exists). If the partition has no instance GUID, ZX_ERR_NOT_SUPPORTED is returned.

§

GetName

Gets the name of the partition (if one exists). If the partition has no name, ZX_ERR_NOT_SUPPORTED is returned.
