Function JxlDecoderReleaseBoxBuffer 

pub unsafe extern "C-unwind" fn JxlDecoderReleaseBoxBuffer(
    dec: *mut JxlDecoder,
) -> usize

Releases buffer which was provided with JxlDecoderSetBoxBuffer.

Calling JxlDecoderReleaseBoxBuffer is required whenever a buffer is already set and a new buffer needs to be added with JxlDecoderSetBoxBuffer, but is not required before JxlDecoderDestroy or JxlDecoderReset.

Calling JxlDecoderReleaseBoxBuffer when no buffer is set is not an error and returns 0.

Parameters

• dec: decoder object

Returns

• The amount of bytes the decoder has not yet written to of the data set by JxlDecoderSetBoxBuffer, or 0 if no buffer is set or JxlDecoderReleaseBoxBuffer was already called.,
