Function JxlDecoderSetBoxBuffer 

pub unsafe extern "C-unwind" fn JxlDecoderSetBoxBuffer(
    dec: *mut JxlDecoder,
    data: *mut u8,
    size: usize,
) -> JxlDecoderStatus

Sets output buffer for box output codestream.

The data is owned by the caller and may be used by the decoder until JxlDecoderReleaseBoxBuffer is called or the decoder is destroyed or reset so must be kept alive until then.

If for the current box a box buffer was set before and released with JxlDecoderReleaseBoxBuffer, bytes that the decoder has already output should not be included, only the remaining bytes output must be set.

The JxlDecoderReleaseBoxBuffer must be used at the next JxlDecoderStatus::Box event or final JxlDecoderStatus::Success event to compute the size of the output box bytes.

Parameters

• dec: decoder object
• data: pointer to next bytes to write to
• size: amount of bytes available starting from data

Returns

• JxlDecoderStatus::Error if output buffer was already set and JxlDecoderReleaseBoxBuffer was not called on it, JxlDecoderStatus::Success otherwise
