class DataTransfer

Defined at line 4448 of file fidling/gen/sdk/fidl/fuchsia.hardware.audio/fuchsia.hardware.audio/hlcpp/fuchsia/hardware/audio/cpp/fidl.h

Data to be transferred. There are two supported ways data may be conveyed, corresponding to the

two members of the DataTransfer union:

1) vmo_transfer: A region within a VMO previously known to the driver. This VMO must have been

established via `PacketStreamControl.RegisterVmos` (if client-allocated) or

`PacketStreamControl.AllocateVmos` (if driver-allocated). Future requests refer to this

buffer by the unique `vmo_id`. Because VMOs are reused across requests, the one-time

cost of pinning/mapping is amortized.

2) data: The payload is provided directly within the message. This mode is intended for

small transfers or control information, not high-throughput streaming.

fidl_xunion_tag_t Ordinal ()

You probably want to use Which() method instead of Ordinal(). Use Ordinal() only when you need

access to the raw integral ordinal value.
