<p>Different Block handling functions use different parts of this structure. Some read some members, other functions write, and some do both.

The members marked for writing will be assigned new values at some point either by calling the given function or by later calls to <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a>. </p>

<p>Size of the Compressed Data in bytes. </p>
<p>Encoding: If this is not LZMA_VLI_UNKNOWN, Block Header encoder will store this value to the Block Header. Block encoder doesn't care about this value, but will set it once the encoding has been finished.</p>
<p>Decoding: If this is not LZMA_VLI_UNKNOWN, Block decoder will verify that the size of the Compressed Data field matches compressed_size.</p>
<p>Usually you don't know this value when encoding in streamed mode, and thus cannot write this field into the Block Header.</p>
<p>In non-streamed mode you can reserve space for this field before encoding the actual Block. After encoding the data, finish the Block by encoding the Block Header. Steps in detail:</p>
<ul>
<li>Set compressed_size to some big enough value. If you don't know better, use LZMA_VLI_MAX, but remember that bigger values take more space in Block Header.</li>
<li>Call <a class="el" href="block_8h.html#ae9b47abc872d0b02c2da9d3fa5a7dacd" title="Calculate Block Header Size.">lzma_block_header_size()</a> to see how much space you need to reserve for the Block Header.</li>
<li>Encode the Block using <a class="el" href="block_8h.html#a2218a49025a0b44f9a6f9d6d24359359" title="Initialize .xz Block encoder.">lzma_block_encoder()</a> and <a class="el" href="base_8h.html#a28cc09bc422d5ba1e0187c9f2af5d957" title="Encode or decode data.">lzma_code()</a>. It sets compressed_size to the correct value.</li>
<li>Use <a class="el" href="block_8h.html#a0eedbd6331d5708ea963260e6f2a92d0" title="Encode Block Header.">lzma_block_header_encode()</a> to encode the Block Header. Because space was reserved in the first step, you don't need to call <a class="el" href="block_8h.html#ae9b47abc872d0b02c2da9d3fa5a7dacd" title="Calculate Block Header Size.">lzma_block_header_size()</a> anymore, because due to reserving, header_size has to be big enough.
