Function AudioComponentInstanceGetComponent 

pub unsafe extern "C-unwind" fn AudioComponentInstanceGetComponent(
    in_instance: *mut OpaqueAudioComponentInstance,
) -> *mut OpaqueAudioComponent

Retrieve the audio component from its instance

Allows the application at any time to retrieve the audio component that is the factory object of a given instance (i.e., the audio component that was used to create the instance in the first place). This allows the application to retrieve general information about a particular audio component (its name, version, etc) when one just has an audio component instance to work with

Parameter inInstance: the audio component instance (must not be NULL, and instance must be valid - that is, not disposed)

Returns: a valid audio component or NULL if no component was found.

Safety

in_instance must be a valid pointer.
