Struct MTAudioProcessingTapCallbacks 

#[repr(C, packed(4))]
pub struct MTAudioProcessingTapCallbacks {
    pub version: c_int,
    pub clientInfo: *mut c_void,
    pub init: MTAudioProcessingTapInitCallback,
    pub finalize: MTAudioProcessingTapFinalizeCallback,
    pub prepare: MTAudioProcessingTapPrepareCallback,
    pub unprepare: MTAudioProcessingTapUnprepareCallback,
    pub process: MTAudioProcessingTapProcessCallback,
}

Available on crate features MTAudioProcessingTap and objc2-core-audio-types and objc2-core-media only.

Note that for 64-bit architectures, this struct contains misaligned function pointers. To avoid link-time issues, it is recommended that clients fill MTAudioProcessingTapCallbacks’ function pointer fields by using assignment statements, rather than declaring them as global or static structs. Field: version The version number of the structure passed in as a parameter to MTAudioProcessingTapCreate(). Must be kMTAudioProcessingTapCallbacksVersion_0. Field: clientInfo Client data that will be passed to the init callback when it is invoked. Can be NULL. Field: init A callback to allow the client to initialize the tap processor. Can be NULL. This callback is called before MTAudioProcessingTapCreate() returns. Field: finalize A callback to allow the client to perform any necessary cleanup. Can be NULL. This callback will be called exactly once when the MTAudioProcessingTap object is finalized. Field: prepare A callback to allow the client to prepare the tap processor (allocate memory buffers, etc). Can be NULL. Note that the callback may be called multiple times. Field: unprepare A callback to allow the client to perform any necessary cleanup for which that is prepared. Can be NULL. Field: process A callback for processing the audio.
