The IMMDeviceCollection interface represents a collection of multimedia device resources. In the current implementation, the only device resources that the MMDevice API can create collections of are audio endpoint devices.
A client can obtain a reference to an IMMDeviceCollection interface instance by calling the IMMDeviceEnumerator::EnumAudioEndpoints method. This method creates a collection of endpoint objects, each of which represents an audio endpoint device in the system. Each endpoint object in the collection supports the IMMDevice and IMMEndpoint interfaces. For more information, see IMMDeviceEnumerator Interface.
For a code example that uses the IMMDeviceCollection interface, see Device Properties.
The IMMDeviceCollection interface inherits from the IUnknown interface. IMMDeviceCollection also has these types of members:
