Function JxlDecoderReleaseJPEGBuffer 

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

Releases buffer which was provided with JxlDecoderSetJPEGBuffer.

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

Calling JxlDecoderReleaseJPEGBuffer 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 JxlDecoderSetJPEGBuffer, or 0 if no buffer is set or JxlDecoderReleaseJPEGBuffer was already called.
