Declaration

func AudioConverterFillComplexBufferRealtimeSafe(_ inAudioConverter: AudioConverterRef, _ inInputDataProc: AudioConverterComplexInputDataProcRealtimeSafe, _ inInputDataProcUserData: UnsafeMutableRawPointer?, _ ioOutputDataPacketSize: UnsafeMutablePointer<UInt32>, _ outOutputData: UnsafeMutablePointer<AudioBufferList>, _ outPacketDescription: UnsafeMutablePointer<AudioStreamPacketDescription>?) -> OSStatus

Discussion

Identical to AudioConverterFillComplexBuffer, with the addition of a realtime-safety guarantee.

Conversions involving only PCM formats – interleaving, deinterleaving, channel count changes, sample rate conversions – are realtime-safe. Such conversions may use this API in order to obtain compiler checks involving the CA_REALTIME_API attributes.

At runtime, this function returns kAudioConverterErr_OperationNotSupported if the conversion requires non-realtime-safe functionality.
