class WireSyncClientImpl

Defined at line 4761 of file fidling/gen/sdk/fidl/fuchsia.storage.block/fuchsia.storage.block/cpp/fidl/fuchsia.storage.block/cpp/wire_messaging.h

Methods to make a sync FIDL call directly on an unowned handle or a

const reference to a |::fidl::ClientEnd

<

::fuchsia_storage_block::Block>|,

avoiding setting up a client.

Public Methods

::fidl::WireResult< ::fuchsia_storage_block::Block::GetInfo> GetInfo ()

Get information about the underlying block device.

Allocates 72 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::OneWayStatus OpenSession (::fidl::ServerEnd< ::fuchsia_storage_block::Session> && session)

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

Allocates 40 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::OneWayStatus OpenSessionWithOffsetMap (::fidl::ServerEnd< ::fuchsia_storage_block::Session> && session, const ::fuchsia_storage_block::wire::BlockOffsetMapping & mapping)

Opens a new FIFO-based session on the block device, providing a mapping which is

transparently applied to device offsets in block FIFO requests.

This interface is intended to be used internally between nested Block implementations, in

order to provide passthrough I/O. For example, a fixed partition map (e.g. GPT) will serve

a Block protocol for each partition, and will respond to OpenSession requests by calling

OpenSessionWithOffsetMap on the underlying block device, establishing itself as the source

for translating client block offsets (relative to the partition start) to absolute offsets.

The client can then communicate directly with the underlying block device, and the partition

offsets can be transparently applied to requests.

Allocates 64 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::GetTypeGuid> GetTypeGuid ()

Gets the type GUID of the partition (if one exists).

If the partition has no type GUID, ZX_ERR_NOT_SUPPORTED is returned.

Allocates 64 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::GetInstanceGuid> GetInstanceGuid ()

Gets the instance GUID of the partition (if one exists).

If the partition has no instance GUID, ZX_ERR_NOT_SUPPORTED is returned.

Allocates 64 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::GetName> GetName ()

Gets the name of the partition (if one exists).

If the partition has no name, ZX_ERR_NOT_SUPPORTED is returned.

Allocates 184 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::GetMetadata> GetMetadata ()

Gets the metadata for the partition.

Fields may be absent if the partition doesn't have the given metadata.

Allocates 16 bytes of request buffer on the stack. Response is heap-allocated.

::fidl::WireResult< ::fuchsia_storage_block::Block::QuerySlices> QuerySlices (::fidl::VectorView<uint64_t> start_slices)

Returns the number of contiguous allocated (or unallocated) vslices

starting from each vslice.

Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.

Allocates 448 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::GetVolumeInfo> GetVolumeInfo ()

Returns the information about this volume and the volume manager it is embedded in.

Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.

Allocates 112 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::Extend> Extend (uint64_t start_slice, uint64_t slice_count)

Extends the mapping of this partition.

The ability to extend the partition is dependent on having sufficient free space on the

underlying device, having sufficient free slots for tracking the bytes in the volume

manager header, and the partition limit (see VolumeManager.SetPartitionLimit).

Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.

Allocates 56 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::Shrink> Shrink (uint64_t start_slice, uint64_t slice_count)

Shrinks a virtual partition. Returns `ZX_OK` if ANY slices are

freed, even if part of the requested range contains unallocated slices.

Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.

Allocates 56 bytes of message buffer on the stack. No heap allocation necessary.

::fidl::WireResult< ::fuchsia_storage_block::Block::Destroy> Destroy ()

Destroys the current volume, removing it from the VolumeManager, and

freeing all underlying storage. The connection to the volume is also closed.

Returns ZX_ERR_NOT_SUPPORTED if the device is not a volume.

Allocates 40 bytes of message buffer on the stack. No heap allocation necessary.
