46<H2>Description</H2>
47<P>Initializes the context structure for streaming the uncompression of the LZ77-compressed data. Use this interface for uncompressing only the number of bytes of data specified by <SPAN class="argument">destSize</SPAN>.<BR>To uncompress all data, use the <A href="CXInitUncompContextLZ.html"><CODE>CXInitUncompContextLZ</CODE></A> function.
48</P>
49<P>
50When the <A href="CXReadUncompLZ.html"<CODE><CODE>CXReadUncompLZ</CODE></A> function is run using this context, the next set of data gets expanded in the region passed by the <SPAN class="argument">dest</SPAN> argument.
51</P>
52<P>
53If this context is going to be reused, it needs to be reinitialized after the expansion of each file is completed.
