[API design] Accessing latency info on the audio thread?

[xris1658]

I noticed that clap_audio_buffer has a field called latency, which indicates "latency from/to the audio interface". Since clap_audio_buffer is only used in clap_process, which is only accessed on the audio thread while the plugin is processing, I can say that latency is only accessed directly from the audio thread.

The question is that I cannot figure out how the audio thread utilizes this info.

As a reference: in VST3 plugin API, the plugin accesses the similar latency info by implementing the IAudioPresentationLatency interface, which is used on the UI thread. From what I understood, the plugin can synchronize the UI elements with the audio stream passing through with this interface. If I'd like to make a plugin that does the same thing with CLAP, the latency info can only be read on the audio thread, thus has to be passed to the UI thread manually, which is quite an inconvenience.
