<div class="markdown level1 remarks"><p>Returning NULL indicates the end of text, which is the position after the last character. This function is called iteratively for each consecutive block, tying together several fragmented blocks in the backing store into a virtual contiguous string. Although applications can implement sparse textual content that  maps only part of the backing store, the application must map any text that is in the range passed to any analysis functions.</p>
