<h1>CKStateChunk Data Structure</h1>
|
||||||
|
<p>
|
||||||
|
NOTE:<br />
|
||||||
|
"Fill Zero" mean that this field still is existed but you should fill zero for it.<br />
|
||||||
|
"Skip" mean that this field is entirely not existed. You should not consider it anymore.

<h2>Buffer Format</h2>
|
||||||
|
<p>
|
||||||
|
This section will introduce the buffer format of CKStateChunk.<br />
|
||||||
|
Buffer format is the real format of CKStateChunk stored in file.<br />
|
||||||
|
<code>CKStateChunk::ConvertFromBuffer</code> and <code>CKStateChunk::ConvertToBuffer</code> can convert between CKStateChunk and its buffer format.
|
||||||
|
</p>
|
||||||
|
<p>According to the value of CK_STATECHUNK_CHUNKVERSION, we split it into 3 different format.</p>
|
||||||
|
<ul>
|
||||||
|
<li>value < CHUNK_VERSION2: Very Old Format</li>
|
||||||
|
<li>value = CHUNK_VERSION2: Old Format</li>
|
||||||
|
<li>value > CHUNK_VERSION2: New Format</li>
|
||||||
|
</ul>
|
||||||
|
<p>
|
||||||
|
The unit of m_DataDwSize is CKDWORD(uint32), not char(uint8).<br />
|
||||||
|
The core data of CKStateChunk is aligned with 4 byte boundary. so this is the reason why the unit of
|
||||||
|
m_DataDwSize is CKDWORD.<br />
|
||||||
|
Every reading and writing of m_pData should notice this unit issue.
|
||||||
|

The core data is filled by various Identifiers following various data.<br />
|

It is related to the function of CKStateChunk.
