35<h2>Description</h2>
36<P>This is the context structure for saving the state of data uncompression when LZ77-compressed data is being read from the Card and undergoing streaming uncompression. The context is initialized by the <CODE><A href="MI_InitUncompContextLZ.html">MI_InitUncompContextLZ</A></CODE> function and used by the <CODE><A href="MI_ReadUncompLZ.html">MI_ReadUncompLZ</A></CODE> function to save the uncompressed state.<BR>
