public delegatevoid SampleFramesEventNativeFunction (IntPtr userData, uint providerId, uint sampleFrameCount);


userDataUser data specified when the handler was set. The actual C type is void*.
providerIdId of the provider. See
sampleFrameCountNumber of sample frames available or overflowed, depending on event type.


Type that represents the native function pointer for handling sample frame events.

Sample frames events are AudioSampleProvider.sampleFramesAvailable and AudioSampleProvider.sampleFramesOverflow.

Importing such a function from a native plug-in would be done this way:

[DllImport(pluginName, ExactSpelling = true, CallingConvention = CallingConvention.Cdecl)]
private static extern void SampleFramesAvailable(IntPtr userData, uint id, uint sampleFrameCount);
