Function AudioCodecAppendInputData 

pub unsafe extern "C-unwind" fn AudioCodecAppendInputData(
    in_codec: AudioCodec,
    in_input_data: NonNull<c_void>,
    io_input_data_byte_size: NonNull<u32>,
    io_number_packets: NonNull<u32>,
    in_packet_description: *const AudioStreamPacketDescription,
) -> i32

Available on crate features AudioCodec and AudioComponent and objc2-core-audio-types only.

Append as much of the given data in inInputData to the codec’s input buffer as possible and return in ioInputDataByteSize the amount of data used.

The inPacketDescription argument is an array of AudioStreamPacketDescription structs that describes the packet layout. The number of elements in this array is indicated on input by ioNumberPackets. On return, this number indicates the number of packets consumed.

Note also in this case that it is an error to supply less than a full packet of data at a time.

Parameter inCodec: An AudioCodec instance

Parameter inInputData: A const pointer to the input data

Parameter ioInputDataByteSize: The size in bytes of the input data in inInputData on input, the number of bytes consumed on output

Parameter ioNumberPackets: The number of packets

Parameter inPacketDescription: The packet description pointer

Returns: The OSStatus value

Safety

• in_codec must be a valid pointer.
• in_input_data must be a valid pointer.
• io_input_data_byte_size must be a valid pointer.
• io_number_packets must be a valid pointer.
• in_packet_description must be a valid pointer or null.
