GetDefaultAudioEndpointNative(DataFlow dataFlow, Role role, IntPtr& device)

The GetDefaultAudioEndpoint method retrieves the default audio endpoint for the specified data-flow direction and role.

public Int32 GetDefaultAudioEndpointNative(DataFlow dataFlow, Role role, IntPtr& device)

Parameters

dataFlow

DataFlow

The data-flow direction for the endpoint device.

role

Role

The role of the endpoint device.

GetDeviceNative(String id, IntPtr& device)

Retrieves an audio endpoint device that is identified by an endpoint ID string.

public Int32 GetDeviceNative(String id, IntPtr& device)

Parameters

id

String

Endpoint ID. The caller typically obtains this string from the DeviceID property or any method of the IMMNotificationClient.

device

IntPtr&

A pointer variable into which the method writes the address of the IMMDevice interface for the specified device. Through this method, the caller obtains a counted reference to the interface.

Returns
