Function libjxl_sys::JxlDecoderReleaseJPEGBuffer

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

Releases buffer which was provided with @ref JxlDecoderSetJPEGBuffer.

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

Calling @ref JxlDecoderReleaseJPEGBuffer when no buffer is set is not an error and returns 0.

@param dec decoder object @return the amount of bytes the decoder has not yet written to of the data set by @ref JxlDecoderSetJPEGBuffer, or 0 if no buffer is set or @ref JxlDecoderReleaseJPEGBuffer was already called.
