class WireSyncClientImpl

Defined at line 21259 of file fidling/gen/sdk/fidl/fuchsia.media/fuchsia.media/cpp/fidl/fuchsia.media/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_media::UsageGainListener>|,

avoiding setting up a client.

Public Methods

::fidl::WireResult< ::fuchsia_media::UsageGainListener::OnGainMuteChanged> OnGainMuteChanged (bool muted, float gain_dbfs)

Called immediately on connection and afterward any time

the usage gain setting changes.

Clients must respond to acknowledge the event. Clients that do not acknowledge their

events will eventually be disconnected.

Note: This API does not have mute reporting implemented; `muted` is always false.

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